Elementary, my dear WSDOT

Some cool tools – aka underground detectives – do the dirty work under SR 203 when we aren't able to

By Frances Fedoriska

A level of "subterranean sleuthing" will help us determine why a portion of State Route 203 suddenly shifted earlier this year. Without Sherlock Holmes around, we can't crack this case without the help of some devices designed for undercover dirty jobs like the one unfolding under the highway between Carnation and Duvall.

Following a landslide in early 2020, we planted multiple devices under mounds of dirt, rocks and debris under the highway. Since then, they've been collecting information needed to design a fix for the slide – in places and times when we can't access the area.
Exhibit C – for "cracks." This gash in the asphalt on SR 203 shows how much the ground underneath
the roadway moved during a slide earlier this year.

Exhibit A: The timeline
Here's a quick recap of how we got here:
  • Early 2020 – A slide causes part of the southbound lane between Carnation and Duvall to give way. Since then the lane has been closed with traffic alternating through northbound SR 203.
  • March 23, 2020 – The global pandemic prompts the Governor to issue a "Stay Home" order to slow the spread of COVID-19, halting most construction in our state to keep workers safe and at home. 
  • June 19, 2020 – King County enters Phase 2 of the "Safe Start" reopening plan. This gives our personnel permission and new guidelines to safely get back to work in the field, investigating the cause of the slide.  
  • July 15, 2020 – SR 203 closes for a day allowing crews to access the area and collect subsurface information from devices installed into the sinking side of the roadway. We also searched for a historic waterline in the northbound shoulder.
Star witnesses: inclinometers and piezometers
Inclinometers measure embankment movement. The metal casing – basically a large, specialized pipe – is placed inside a hole drilled into the roadway and then bends when the ground or road around it moves. A probe is lowered into the casing to measure any deformations to determine how much movement happened since the previous reading.
Two key devices, both resembling metal coffee tins, tell us what is happening under the highway by
measuring movement without tearing up the road.

Piezometers monitor groundwater levels underneath the road. This is crucial to predicting future movement needed to prevent future slides. An open standpipe piezometer -- a long, narrow pipe placed inside a bore hole -- collects groundwater. Periodic manual readings of how deep the water level is shows whether there's a change – or movement – in the ground below that allows water to seep up or out of the ground.
In late July we took manual readings from the piezometer to monitor groundwater levels under the roadway.

Next steps
It will take a few weeks to assemble all the clues and translate the data we've collected into a confirmed source of the slide. Once we know the cause, engineers will design a solution that fixes the damage done and prevents future occurrences so we can safely reopen all lanes of SR 203.
Masked up and physically distanced, a crew member enters measurements into the system. The data logged in the
field will be analyzed by our geotechnical team in Olympia.

Thank you for your patience
We understand travelers are frustrated with the delays and speed at which this project is unfolding. We are too. At this time, there is no date for when construction may begin, but our goal remains getting started before the next rainy season.

To stay up to date on the developments, sign up for WSDOT's King County updates. A project webpage will be added to the WSDOT website once this mystery is solved.

Building a bridge over I-5 in one weekend, and how you can help

By Laura Newborn

The most dramatic sign of progress on our SR 167 Completion Project is a new bridge in Fife that's about to take shape in just one weekend.

On August 28 and 29, our contractor, Guy F. Atkinson Construction, will close both directions of I-5 between Federal Way and Fife to move 10 gigantic girders into place for the new 70th Avenue East Bridge. It's a heavy lift. Each girder is 220 feet long - almost the size of a 747-8's wingspan. Each one is 9 feet tall, 4 feet wide and 231,000 pounds. Installing these girders takes plenty of coordination, choreography and skill.
This bridge girder shows just how big these record-breaking girders are. The one belongs to the future southbound I-5 Puyallup River Bridge and is 223-feet-long. The Fife girders are 220-feet long. Combined, these two projects set the record for the largest pre-stressed concrete girders made in the US. They are made in Tacoma by Concrete Technology Corp.

Closing I-5 between Federal Way and Fife
Safely lifting loads this large across the highway requires a full closure of I-5 for two consecutive overnight periods. Each night, five girders will make the 5-mile, 45-minute journey from Tacoma's Concrete Technology Corp. to the bridge site in Fife. Cranes stationed on the southbound and northbound roadways will then guide each girder to its predetermined spot. Five girders one night and five the second night.

We chose weekend overnights for the work as they are the least-traveled times on I-5, but we understand there's never a good time to close a major interstate. Backups could be significant in both directions. And that's where we need your help. If possible, please avoid the area and skip discretionary trips during these hours:

Friday, August 28 and Saturday August 29
  • I-5 lane closures begin at 8 p.m. on Friday
  • All lanes of I-5 will close at 11p.m. between 54th Avenue East in Fife and SR 18 in Federal Way
  • Lanes start to reopen by 8 a.m. Saturday
  • All lanes will reopen by noon Saturday
Saturday August 29 and Sunday August 30
  • I-5 lane closures begin at 8 p.m. Saturday
  • All lanes of I-5 will close at 11 p.m. between 54th Avenue East in Fife and SR 18 in Federal Way
  • Lanes start to reopen by 8 a.m. Sunday
  • All lanes will reopen by noon Sunday
We need help from drivers
Drivers who must travel between Seattle and Olympia during the closure hours are advised to use SR 18, SR 167, and SR 512, which can accommodate the most traffic. The SR 99 detour provides access back to I-5. Southbound I-5 travelers headed to downtown Tacoma, Gig Harbor or points beyond will want to consider the SR 99 detour.

Benefits of building a bridge this way
One of the reasons we chose to build a bridge with these exceptionally long girders was to avoid long-term traffic impacts. Shorter girders would have required us to widen I-5 and build columns in the median – work that would have brought prolonged lane closures. The longer girders need one weekend to install. You can watch bridge construction and the girder lift on our real-time construction cameras.

In the end, this project will be worth it. When it opens in mid-2021, the new 70th Avenue East Bridge will greatly improve travel in the area by reducing congestion, improving freight mobility, and providing new options for people who walk and bike.

Reallocating space to support economic recovery and healthy lifestyles

By Beth Bousley

In response to the pandemic, communities are looking for creative ways to support their businesses while taking care of their residents. Some have approached us to reallocate space on public roadways to allow for more freedom for retailers and restaurants to operate outdoors and for people to stroll, roll, cycle, dine and shop while more easily staying six feet apart.

So we've come up with a plan. The Safe, Healthy and Active Streets Program.

Safe, Healthy, and Active Streets Program
As we began receiving requests from different communities interested in temporary lane reallocation, we developed a set of parameters for considering and responding to these requests.

Under Gov. Inslee's Safe Start Plan, we partnered with the Washington state departments of Health and Commerce to provide communities more access to public roadways to support business recovery and active, healthy lifestyles. This is one more tool for communities to consider as they think about the health of their residents and economic recovery for local businesses.

The Safe, Healthy and Active Streets Program (pdf 80 kb) allows temporary lane reallocations on some state roadways. The goal is to increase space for people walking or biking, or create outdoor seating for restaurants and sales areas for retailers, while maintaining physical distance to help reduce exposure to the virus. Across the state, 458 miles of state routes meet the criteria because they are located in a town or area where people live and have speed limits of 35 mph or less.
Parklet in White Salmon provides outdoor seating for restaurant.

The temporary lane reallocation is not one-size-fits-all. Some communities, like Bingen and White Salmon, are replacing a parking space or two with outdoor restaurant or brewpub seating. In Pullman the pandemic reignited the community's interest in the Central Business District Master plan, which is designed to enhance the energy and public spaces in the downtown corridor. By implementing a trial run with temporary lane reallocation along Main Street (which is also a segment of SR 270), Pullman is testing and getting community feedback on elements of the plan at a cost of less than $5,000.

With the approval of the Pullman City Council, we joined the city in looking at the street's traffic volumes and determined Main Street could function adequately with two lanes. They worked together to develop the plans for revisions. Some intersections have been reconfigured to create shorter crosswalks, reducing the distance for people crossing the street and at the same time making it easier for stores and restaurants to spill out onto the sidewalk to help customers remain physically distant from each other. A lane of traffic was converted to a protected bike lane and back-in angled parking, which is serving to calm traffic to help people comply with the posted speed limit. With the protected bike lane, people on bikes have separation and protection that makes it more comfortable to ride than being right next to moving motor vehicles. Back-in parking adds more capacity than other options like parallel parking. It is also safer, because passengers don't need to exit the car into traffic and drivers have better visibility when re-entering traffic.

This trial period will last through the summer and early fall to give the community a sense of how the changes worked with and without Washington State University students present. So far, city officials say that people like the bike lane and new uses of the sidewalk. Crossing the street feels safer. The back-in angled parking presents some challenges. One truck driver shared that he finds the stalls too small, emphasizing that Pullman is an agricultural community with lots of trucks. He wants to see the program through to the end, but wants to make sure Pullman implements what feels right for the community.

WSDOT and the city looked at the street's traffic volumes, and determined
Main Street could function adequately with two lanes.

The extra space was used to change the parallel parking on the south side of Main Street to back-in angled parking.

There is also a new bike lane protected by temporary barriers.

In Pullman, the barriers will be gone by October and auto traffic will flow again.

Opening up portions of roadways helps retailers, restaurants and other businesses adapt to new operating requirements by giving customers greater access at their locations. This includes outdoor seating at restaurants on sidewalks or part of a roadway as well as curbside pickup locations for retailers.  These steps strengthen communities and let people experience their main street and downtown commercial neighborhoods in new ways.

Active transportation, like walking and biking, supports physical, mental and emotional health. Providing this extra public space encourages people and families to get outdoors and participate in more physical activities, which is especially important today to help cope with the stress of COVID-19. It also provides more room for such activities, especially in towns with narrow sidewalks that aren't conducive to physical distancing or lack ADA accessibility. Our COVD-19 transportation dashboard is showing increases in walking and bicycling well above the same time last year, while driving is down.

Helping communities
SR 14 parklet in Bingen provides outdoor seating for restaurants

This is a community-led program and happens only if a community requests it in a specific location for a limited duration (up to 90 days although it could end sooner or be extended). Currently, Bingen, Pullman, and White Salmon are in the program. A number of communities across the state including Seattle, Everett, Bellevue and Edmonds have opened parking areas or lanes in their city's commercial district for increased open space and business access or have temporarily changed neighborhood streets to provide more walk/bike space while continuing to provide access for drivers who live there or who are providing services or deliveries. Cities with state routes in their business districts should first get buy-in from their community stakeholders, then contact us. Counties can also propose locations in population centers that aren't incorporated as cities or towns.

Every project must meet state safety standards and be approved before implemented, and we will work with them to ensure they meet the following criteria:
  • Eligible state highway locations will be on roadways with 35 mph speed limits or lower and within population centers with demonstrated lack of space for physical distancing for walking, bicycling or other forms of active transportation.
  • Local jurisdictions will ensure that they've communicated with the people and businesses affected by the changes and that they report on how the roadway changes work.
  • The duration of temporary lane reallocations will be for up to 90 days, but could vary depending on the agreement with each city.
  • A traffic management plan that will enable people using every mode of transportation to get to their destinations is in place.
In these extraordinary times our goal is to support the wellbeing of people and businesses in interested communities, and ultimately throughout our state.

2020 isn’t a normal year – including for our road maintenance work

By Barbara LaBoe

2020 has come with a list of challenges and “new normals” for everyone, and that includes the people working to keep our state roads maintained in the midst of a pandemic.

The pandemic and subsequent revenue reductions have left our crews months behind their normal workload and now trying to catch up while also encountering new obstacles. And that's on top of the backlog we were already facing before the pandemic struck.
Our crews are working night and day to complete needed maintenance work, but pandemic delays
and new restrictions means they can't get to everything they normally would this spring and summer.

Simply put, we're not able to do all that we have in past springs and summers. And we know that means the traveling public will notice the difference.

This is particularly tough for our crews, who take immense pride in the roadways they maintain within their communities and the work they do day in and day out. The delays are due to limits on hours and personnel – not the effort of our crews.

How did we get here?
We were already struggling to maintain infrastructure after decades of underfunding for work needed to maintain and preserve our infrastructure. What made it tougher was the pandemic.

The safety of our crews is our priority, so to keep them safe and slow the spread of the virus, in March we sent most of our maintenance crews home. (We also shut down construction projects across the state). This meant most work usually done in the spring – including summer prep – wasn't able to take place. And now subsequent pandemic-related revenue reductions and an April hiring freeze mean there is less money and fewer workers for both summer work and winter prep.
When crews can't maintain 6 feet of distance to complete a task, such as guardrail repair, they must don even more protective equipment, such as these Powered Air Purifying Respirators, which use battery packs to supply filtered air.

While our crews are back, they returned slowly as part of turning the dial on Safe Start and each county's reopening phase. Once on the job they had new protocols and gear that are important but also slows down their normal work flow. Then in June mandatory state government furloughs and hiring freezes were announced, leaving crews with even less time to complete the already backlogged work and unable to hire the temporary summer crews that normally assist our efforts.
New safety standards are important but also require more rest and hydration breaks
as crews work in warm summer months.

Weather-dependent work limits our options
Much of our work is season- and weather-dependent, so pushing it further into 2020 to make up some of the missed items won't work in all cases. Some examples of that are:
  • Roadside mowing. Spring mowing wasn't able to take place and mowing during hot summer months is a fire hazard. So we need all travelers to be extra cautious of fire dangers this year to help prevent brush fires.
  • Roadside trash, which was already a problem, is one the items our crews have to forego to prioritize safety repairs and work. And our volunteer Adopt-A-Highway crews are suspended for their own safety during the pandemic. This makes prevention even more crucial – please secure all loads and properly dispose of any trash you accumulate traveling.
  • Roadway crack repairs. These are best done in early spring while the cracks are still at their largest. Filling them in summer isn't as efficient since the cracks shrink as the warmer roadway expands, so a new repair can fail as soon as the roadway freezes again in the winter.
  • Paving is delayed in areas due to spring delays and overall backlogs. That also means less pavement striping and painting, which are also summer work staples and require long stretches of dry weather.
  • Some work – such as installing new light poles – has been delayed because it requires crews working closely together, which requires additional safety equipment. (Emergency work requiring close contact still continues).
None of these decisions or new adjustments are easy – it's a struggle to not accomplish everything we would in a “normal” summer. But 2020 is a year of altered expectations for everyone and this is yet another unfortunate example.

Please be patient with any delays or reduced service you see on our roadways and take any precautions you can to help ease the stresses on the system. It's an adjustment for everyone, but we also know that working together we can make it through this just as we've met other pandemic challenges.

Highways not safe places to park, camp

By Mike Allende

One of the great things about our state is the recreation. Mountains, rivers, forests, ocean beaches. We have it all. And while the safest thing to do as we navigate through the COVID-19 pandemic is to stay close to home, we know that people are looking to get outside during the summer.

Recently we've received a lot of messages about people going to recreation areas only to find the parking lots full. Rather than find a less populated place to enjoy the outdoors, they park alongside the highway. This is not a great idea and we want everyone to be safe in whatever choice they make.

Highway shoulders are designed for emergencies. In many cases, people are parking on shoulders too narrow for their vehicle to fit without being partway on the highway. Not only does this lead to significant traffic congestion – especially on weekends – as drivers need to slow down to avoid hitting an illegally parked car, it's also a huge safety issue.

Parking on the shoulder also means people are walking along the highway, often carrying things like kayaks, canoes and coolers which limit mobility and their ability to see oncoming traffic. No one should be walking along most highways unless it's an emergency.

In particular, we've seen issues on US 2 at Eagle Falls – between Index and Skykomish – where very large crowds are parking in no-parking areas and driving dangerously, leading to significant congestion and big safety issues. We're seeing passing in no-passing zones, dangerous u-turns, people walking across the highway and parking vehicles too close to – and sometimes partway on – the highway. This is in a remote area with a 60 mph speed limit so any one of these actions could lead to tragedy. And, these issues also make it more difficult for emergency crews to respond to incidents as needed. We're working on plans to help with the situation, and the Washington State Patrol is working on enforcement but we also need the public's help in keeping everyone safe.

We know the draw of hiking to a waterfall or kayaking down a river is huge, maybe now more than ever. But we ask you to do it safely. Leave early and remember to have a backup plan if the place you want to go to is full – and that backup plan shouldn't include parking on the highway. Remember that it's still incredibly important to maintain a safe physical distance, and the more full a parking lot is, the harder that may be. It's a big state, with a lot of areas to enjoy, so please find safe areas to do so.
Camping at rest areas is illegal and those who use the safety areas should limit them
 to 8 hours for passenger vehicles and 10 hours for commercial vehicles.

Speaking of safe areas

We've heard from travel groups like AAA that this could be a big summer for camping and road trips. Like parking lots at state parks, many camp grounds are already filled up. So a reminder that camping at safety rest areas is illegal.

Rest areas are there for safety, to allow freight haulers and other travelers a place to rest and take a break. The law allows for commercial vehicles to stay at a rest area for 10 hours, and non-commercial travelers to stay for eight hours.

It is not legal for people to set up tents and other sleeping accommodations at a rest area. Does it happen? Yes. We work with the Washington State Patrol to enforce those laws but there's a lot happening all over the state and law enforcement has to prioritize what it can get to.

We need the parking lots of rest areas to stay relatively clear to allow for those who need them for safety to be able to access them and for our crews to be able to maintain the facilities. We can't have them filled up with campers.

We want everyone to be able to have a safe summer. Please follow the parking and camping rules, whether at a park or a rest area, and we can all enjoy the wonderful parts of our state before the rainy season moves back in.

Big changes coming to I-5 in Vancouver

Plan for delays this summer in advance of the Interstate Bridge Closure, Sept. 12 - 20

By Tamara Greenwell

Anyone who travels southbound on Interstate 5 in Vancouver is all too familiar with traffic backups and delays. Vancouver is the state's second-fastest-growing city according to the Office of Financial Management's (pdf 1.4 mb) population report. Continued growth and development are contributing to congestion on area highways that is beginning earlier in the morning and lasting later at night. The solution is not always adding more infrastructure but rather using existing infrastructure in a smarter, safer, and more efficient way.

This summer, we're installing new smart technology upgrades and adding a bus-only lane on southbound I-5 between 99th Street and the Interstate Bridge to help improve the flow of traffic and safety. While we're juggling mandatory furloughs and COVID-19 safety guidelines, we're working to get these projects completed ahead of the Interstate Bridge Trunnion Replacement project, which will close the entire northbound span of the Interstate Bridge on I-5 from September 12-20 and will have a ripple effect on travel throughout the region.
Traffic backup on southbound I-5 in Vancouver

New smart technology upgrades on I-5

First let's talk about these new lower-cost tools we're installing, including a combination of new traffic cameras, adaptive ramp meters, electronic message signs and traffic/weather sensors along a 4-mile stretch of the interstate between 78th Street and the Interstate Bridge. We chose to install Active Traffic and Demand Management (ATDM) tools along this stretch of I-5 because it's an area where we see consistent congestion and a significant number of crashes. This stretch of highway also has several on-ramps spaced close together, which causes traffic to stack up as folks entering the highway merge onto the interstate. Intermittent lifts of the Interstate Bridge and stalled vehicles also cause backups.
Electronic message signs provide real-time travel information

The pieces of the new ATDM system will work in tandem so we can provide you with real-time changing roadway conditions like weather information, changes in speed due to congestion, a crash or bridge lift, and lane closures due to a stalled vehicle, crash, police activity or construction. With earlier warning of an upcoming slowdown or lane closure, you can start adjust your driving before traffic stops. We put together this nifty video so you can see how it works.

The system includes adaptive ramp meters which are currently being installed along southbound I-5 at 78th Street, Main Street, State Route 500/39th Street, Fourth Plain Boulevard and Mill Plain Boulevard. We're also upgrading the existing ramp meter at SR 14/Washington Street in downtown Vancouver. These meters aren't the ramp meters of yesterday. Adaptive meters respond to real-time traffic conditions and turn on automatically when traffic starts to stack up. To maximize the existing roadway and minimize traffic backups onto nearby streets, newly installed signs and roadway striping will allow drivers accessing southbound I-5 via Fourth Plain Boulevard, Mill Plain Boulevard and SR 14/Washington Street to use the shoulder of the ramp as an additional lane to line up at the ramp meter when it is turned on.
Adaptive ramp meters on southbound I-5 in Vancouver

Adjusting the flow of vehicles merging onto I-5 at a consistent rate helps synchronize the flow of traffic to get more vehicles through this stretch of I-5 than is the case today. Another benefit to maintaining consistant traffic flow is that it helps to reduce the severity and frequency of crashes. While you might wait a little longer at a ramp to get onto I-5, you'll get more reliable and safer travel on the interstate, helping you reach your destinations sooner and safer.
Crews installing electronic message signs over southbound I-5 in Vancouver

The system will also help reduce the number of people who skip around traffic backups on I-5, using downtown streets as a bypass. Currently we see about 35 percent of the drivers who exit I-5 at Main Street get right back on again in downtown Vancouver. By providing reliable travel on I-5, through travelers are more likely to stay on the interstate.

We're about halfway done with the installation of this smart technology upgrade. Later this month, we'll close I-5 between the I-5/I-205 split and SR 500 from 11 p.m. Friday, July 24 until 6 a.m. Saturday, July 25, to install a new high-tech electronic message sign bridge, which will span the full width of the interstate, across all lanes in both directions.

Please be patient as we test the system to make sure it's all connected and working in tandem before the system “goes live” in September. While we can't fully stop congestion (unless more people continue to telework or work alternative hours), these new smart technology tools will work to maximize our existing roadway system, providing real-time information to help reduce traffic backups and delays, all while improving safety.

Bus-only lane on I-5 between 99th Street and the Interstate Bridge

To provide more reliable travel times for transit users, we're partnering with C-TRAN to build a bus-only lane using the left shoulder on southbound I-5 from the Northeast 99th Street Transit Center in Hazel Dell to the Interstate Bridge. During weekday peak travel times when travel speeds drop below 35 mph, buses will be able to use the left shoulder of the interstate to bypass traffic backups. The bus-only lane is reserved for transit buses and are not designed to carry large amounts of traffic.
How new ATDM tools and the bus-only lane will look when construction is complete

The bus-only lane will look and operate like any other shoulder and have a minimal effect on traffic. Newly installed signs along the roadway will let you know when buses are using the lane. The shoulder will always be available for disabled vehicles, incident response and emergencies (bus drivers are trained to go around these incidents). This project helps us maximize use of the existing roadway and provide reliable travel times for transit users.

Interstate Bridge Trunnion Replacement Project

COVID-19 and furloughs have certainly changed how we work, but we're still on schedule to get the ATDM and Bus on Shoulder projects completed ahead of the Interstate Bridge Trunnion Replacement project, which will close the entire northbound span of the Interstate Bridge from September 12-20. During the closure, crews will replace mechanical parts that help lift and lower the 103-year-old bridge.

Vehicles, pedestrians, and bicyclists in both directions of travel will share the three existing lanes and sidewalk on the southbound bridge span, resulting in heavy traffic and long delays in Vancouver and Portland on I-5, I-205, I-84, SR 14 and local streets.

If we're going to keep traffic moving during the closure, we'll need everyone's help. Consider options such as delaying or shifting trips, biking, taking transit, or working remotely when possible. If travelers do not change their driving habits during the bridge closure, and if traffic is at normal levels, the length of backups on I-5 may double to four miles and the region may experience up to 16 hours of congestion per day.

After the bridge closure, travel delays will continue on southbound I-5 near the Interstate Bridge while crews close one lane of I-5 for additional work for seven full days and nights, which will create delays for morning southbound travelers. Whether you take a vacation, work from home or use public transit, it'll be important to plan ahead so you're not stuck in traffic due to construction this summer and fall. We have some great tools to help. You can get real-time travel information via our mobile app or sign up to receive email updates.

Interstate Bridge Replacement Program

With work to replace the trunnion on the Interstate Bridge happening this year, many folks have asked what's happening with long-term efforts to replace the bridge. Recognizing that transportation challenges associated with the aging structures remain unaddressed, both Washington and Oregon dedicated funding to restart Interstate Bridge replacement work in 2019 and each state legislature formed a committee with eight representatives to provide direction and oversight. In fall 2019, Governors Jay Inslee and Kate Brown signed a Memorandum of Intent announcing the restart of Interstate Bridge Replacement Program efforts and directed ODOT and WSDOT to open a bi-state office to complete this work.

Right: Interstate Bridge lift in progress

Recent efforts have focused on reengaging partners through a facilitated workshop process and bringing on critical staffing resources. This includes the hiring of a new program administrator to lead the bi-state program office and selecting consulting firm WSP to provide specialized expertise to support program work. The goal is to begin the next phase of program development work this summer, including technical analysis and the start of community engagement work. This will include the formation of two advisory groups as part of broader, comprehensive community engagement efforts with a wide range of stakeholders to identify a bridge solution that reflects community values and can build broad regional support. You can sign up to receive email updates on this work, including public meeting notices and ways to stay engaged.

Final filling begins for the Battery Street Tunnel

By Laura Newborn

The final ingredient in the layer cake that is filling up Seattle's Battery Street Tunnel is being mixed starting this month. Crews have begun pouring a special type of concrete into the tunnel through ventilation grates and holes in the tunnel's roof. This flowable material will fill in the remaining space within the old SR 99 highway tunnel.

Crews working for the contractor, Kiewit, are starting the pouring at Denny Way, the tunnel's north end. The low-density cellular concrete (LDCC) is mixed on-site with mobile equipment staged adjacent to Borealis Avenue. The mixing plant will stay there for several weeks, then move to the Battery Street Tunnel's south portal, which is adjacent to First Avenue. Over the next several months, crews will pump LDCC from the south portal area using a series of  hoses placed along Battery Street.
LDCC mixing equipment staged along Borealis Avenue, just south of Denny Way

What is low-density cellular concrete (LDCC)?
LDCC is produced by mixing water and slurry (a liquid form of concrete) and then injecting a foaming agent. This process produces a kind of concrete meringue that is lightweight and does not get as hard as typical concrete. The material's lightweight property helps protect the utilities beneath it from excess weight, while its lower strength will allow future crews to dig through it when required to reach those utilities. A 5-gallon bucket of LDCC weighs about 20 pounds, versus 100 pounds for standard concrete.

This final stage of filling will use approximately 40,000 cubic yards of LDCC to fill the roughly nine vertical feet left in the tunnel. This is a lot of material – by comparison, CenturyLink field reported using about 10,000 cubic yards of concrete in its construction.

The LDCC is the third type of fill material crews have used in the Battery Street Tunnel. First, crews poured crushed rubble produced from viaduct rubble into the tunnel with trucks from the surface. This spring and summer, crews have been filling the tunnel with Controlled Density Fill concrete (CDF) around the new utilities to protect them from heat and impact. The LDCC is the final layer in the cake, filling in the headroom between those utilities and the tunnel's roof.

What should I expect during construction?
People traveling in the area should expect single-lane closures on Battery Street and cross streets between First and Sixth avenues, and along Borealis Avenue between Sixth Avenue and Denny Way. The batch machinery and idling trucks will also produce an increase in noise and possible vibration.
The mobile LDCC mixing plant staged along Borealis Avenue

More work to come
Fully filling the Battery Street Tunnel is not the end of the job. Once the LDCC is poured, crews will be able to turn to improving the surface of Battery Street. This work has already begun on some blocks, and includes patching over the tunnel's ventilation grates, building new sidewalk and ADA-compliant ramps, and installing new street lighting. The tunnel's south portal has been the construction staging yard for the job and will be turned into a slope and then handed over to the City of Seattle. All work on the project is expected to conclude in 2021.

In an abnormal year, fire season returns as usual

By Mike Allende

This year has been an unusual one, for many reasons. Put simply, few things are the same as they've been in the past.

But one thing that is the same? Fire season has arrived, as it so often does this time of year. As we've seen the past several weeks, fires along our roadsides have increased as we've gotten into the dry weather of summer. It's an unwelcome return as now more than ever, we need the public's help in preventing in small sparks that could ignite into a full-fledged blaze.
During dry seasons brush fires like this recent one in Wenatchee can
spread quickly and present extreme dangers to surrounding areas.

Why now more than ever? Well, again, it's not a usual year.

Our maintenance crews work hard to keep areas near roadways mowed for fire season to reduce brushfire risks. COVID-19 pandemic has affected that work, and now crews are furiously trying to catch up.  Add to that, important but bulkier coronavirus safety equipment, means keeping up with all the maintenance needs throughout the state is a monumental task.
This is the time of year when we see a rise in roadside fires, especially east of the Cascades like this recent fire in Wenatchee.

In the case of vegetation management, that means some areas have not been mowed as much as we'd like. Most of our mowing takes place ahead of the dry season because mowing can present fire hazards as well, so many areas that we would have normally maintained in the spring won't be mowed, at least anytime soon. And that's why we need your help more than ever.

So what can you do?
  • Always properly dispose of cigarettes, fireworks or anything else with a flame. Never toss them out of a vehicle window.
  • Keep your vehicle off of dried grass. Pulling your vehicle into a field with dry grass can spark a fire from the heat of the undercarriage or wheel bearings.
  • Make sure your vehicle and any trailers and equipment are in good working order before heading out. This reduces the chances of vehicle fires which can grow into larger fires. It also helps you avoid getting stranded along the highway.
  • Carry extra water in your vehicle during the summer. Not only might you need it to drink, but you might need it to help douse a fire. It's always a good idea to have some in case of emergency.

During dry conditions it doesn't take much to start a brush fire, like this recently near I-5 in Tacoma, and we need the public's help to limit them.

One thing in particular we're concerned about this year is people taking road trips in RVs and larger vehicles that they aren't used to. These vehicles often have safety chains and it's absolutely vital that you make sure those chains do not drag on the pavement. That little bit of carelessness can cause sparks that can quickly explode into a fire. Be sure to give your vehicle a good look before leaving and be sure everything is secure.

An update on Amtrak Cascades as we move through the summer

By Janet Matkin

As with many other transportation modes, 2020 is proving to be a challenging year for Amtrak Cascades service. The spread of COVID-19 led to large drops in ridership, Canadian border closures, new safety and distancing protocols to protect passengers and staff and significant decreases in revenue.

Amtrak Cascades is currently only operating one daily roundtrip between Seattle and Eugene, including Portland and all other stops in between. All other train service, including all service north of Seattle due to the border closure, is suspended. We continue to monitor ridership levels and will start adding more trips as demand increases. Ridership is down more than 90% below levels as at the same time last year and we continue to follow the Governor's directives related to non-essential travel. This includes limiting ticketing on the trains to 50% capacity to allow plenty of room for physical distancing. Our ultimate goal is to return to a full schedule when it's safe and smart to do so.
Amtrak's Horizon equipment now operating in the Cascades corridor

Train equipment

Amtrak recently delivered Amtrak-owned Horizon train cars to Seattle to replace the Talgo Series 6 trainsets taken out of service in June 2020. This interim Horizon equipment will remain in service on the Cascades route until new trains are manufactured and delivered in the years ahead. In addition, the Talgo Series 8 equipment owned by the Oregon Department of Transportation will continue to operate in the corridor and Amtrak is evaluating adding other interim equipment as demand for service increases.
Consistent with our fleet management plan and as recommended by the National Transportation Safety Board, we are disposing of our two Talgo Series 6 trainsets and spare cars this summer. Information on this competitive bid process is posted on our web pages, with bids due by Aug. 3, 2020.

A new Charger locomotive will be delivered to Seattle by September to replace the one lost in the 2017 derailment. It's being paid for with insurance proceeds from Amtrak. Locomotive 1408 was manufactured at the Siemens facility in Sacramento – the same site all our other locomotives were crafted – and is now at the Transportation Technology Center test site in Pueblo, Colorado. It will be moved to Washington once testing is completed.

Point Defiance Bypass

We continue to meet bi-weekly with Sound Transit, Amtrak, ODOT and Federal Railroad Administration to move forward on the return to the Point Defiance Bypass between Tacoma and DuPont. As the track owner, Sound Transit is leading those discussions and managing the schedule and next steps.

Currently, Sound Transit is developing its Rail Activation Plan related to safety criteria, outreach activities and processes they need completed before they will approve track testing and Amtrak crew qualification. Once those activities are underway, Sound Transit will determine a date for returning passenger rail service to the Point Defiance Bypass.

When service returns to the Bypass, the demand for intercity travel increases, the pandemic risk is minimized and the state transportation budget issues are resolved, we will move forward with adding two more daily roundtrips between Portland and Seattle. These will offer passengers both an earlier morning and later evening trip in each direction, allowing both business and leisure travelers to take day trips back and forth between the cities. We do not have a date when this will happen.

The years ahead

Despite the challenges facing Amtrak Cascades service in the years ahead, we're committed to continue to provide memorable intercity passenger rail service in the Pacific Northwest. The Cascades route is one of the most scenic and popular routes in all of North America. We look forward to the return of riders and the expansion of service in the years ahead.

Even ‘simple’ projects can have complications, so we prepare

Plan ahead for night closures on SR 99 Duwamish River Bridge in Seattle

By Tom Pearce

We have a saying around the office – there’s no such thing as a simple paver. On the surface a project to repave a section of highway may not look like a big deal, but sometimes things happen and that project quickly gets complicated.
Some of the existing steel deck grids have large patches where steel has broken.

On Sunday night, July 19, we’ll begin three weeks of weeknight closures, from 10 p.m. to 5 a.m., on the northbound State Route 99 Duwamish River Bridge, aka the First Avenue South bridge, in Seattle. Our contractor crews are going to replace some worn sections of the steel deck. When we started planning, this looked like a fairly standard preservation project. Then the West Seattle Bridge closed.

Uh oh.

Suddenly, the 100,000-plus vehicles that used the West Seattle Bridge each day had to find an alternate route. A lot of those trips moved onto the SR 99 Duwamish River Bridge, which already carries more than 50,000 trips a day.

See what I mean about no simple pavers (or bridge deck repairs)?
Travelers will have the choice of several other bridges
while the northbound SR 99 Duwamish River Bridge is closed.

Immediately after the West Seattle Bridge closure, we started looking at different options for getting into and out of Seattle besides the Duwamish River Bridge. We also worked with the Seattle Department of Transportation – which manages and maintains the West Seattle Bridge – to figure out alternatives and how to tell people about them. These alternatives include bridges in South Park, Tukwila International Boulevard, West Marginal Way and even Interstate 5.

Initially the Spokane Street lower bridge wasn’t on the table. That bridge is only one lane in each direction and is the main access point for businesses on Harbor Island – definitely not capable of handling more than 100,000 vehicles a day. And for the most part, it’s still not an option. However, things are different at night. There’s a lot less traffic – enough that SDOT is comfortable with letting all vehicles use the bridge during the overnight closures. So now we have that as an alternate as well.

People still need to limit their trips on the lower Spokane Street bridge, even at night. If you’re traveling after dark, you can help by using other alternate routes, depending on your starting and ending points. For example, if you’re at the south end of West Seattle, consider going east to Tukwila and take Tukwila International Boulevard or I-5. If you’re headed for Bellevue or points east and normally would use I-90, think about trying SR 518/I-405 to get there. The highway system provides plenty of options.

While there are no simple projects, there may be some relatively simple solutions to travel issues. We’ll do our best to plan for and provide ideas to help you get where you need to be.

Shift to the right, shift to the left, straight to the finish

Lots of movement coming up on I-5 project in Tacoma

By Nick VinZant and Cara Mitchell

The Macarena, the Electric Slide, the Chicken Dance; every good dance craze has steps we can all follow. We are about to go through the same thing with some travel lane shifts on Interstate 5.

Over the next year, design-build contractor Atkinson Construction will temporarily relocate lanes along I-5 near Portland Avenue in Tacoma. The shifts will keep people moving around our work zones while we finish widening and drainage work along this portion of the highway. This work brings us that much closer to finishing the final funded HOV project on I-5 through Tacoma. An end that will ease congestion on I-5, add HOV lanes, build a new bridge over the Puyallup River and cap off construction. YAY!

Traffic Shifts

A series of lane shifts on I-5 will start later this July near East Portland Avenue to East McKinley Way. We know these shifts will bring a new experience for the traveling public, so we will be communicating often about what is happening and when. As a starting point, here is what I-5 looks like now, before we shift lanes.
Map of the current I-5 layout
The current setup of I-5 in our project area as of July 1, 2020.

Step One: Close a ramp, close a lane and shift an exit
The first stage of changes to I-5 moves the Portland Avenue exit west and reduces the I-705 on-ramp to one lane to allow for concrete paving without any full ramp closures.

The first and biggest traffic shift drivers will notice takes place between Portland Avenue and the I-705 on-ramp to northbound I-5. Over the past year, construction crews widened northbound I-5 in this area. Now we have to realign the northbound I-5 exit to Portland Avenue.

Here’s what will happen: starting as early as July 22, we will move the Portland Avenue exit about a quarter of a mile west toward I-705 (also known as the Tacoma Spur). New signs and lane striping will be in place to alert travelers when to exit. Adjusting the location of the exit allows the contractor to keep it open during the daytime, and drivers won’t have additional detours to contend with. Northbound I-5 will remain three lanes wide, with an additional lane exiting to Portland Avenue during those times. Travelers can expect to see overnight lane and ramp closures as well.

At the same time, the northbound I-5 exit to Portland Avenue is shifted, one lane of the I-705 on-ramp to northbound I-5 and the entire SR 7 on-ramp to northbound I-5 will close.

The goal is to get this work done as quickly as possible, so cross your fingers for some dry weather days. We estimate this portion of work will be complete one month after the shift begins.

Step Two: Northbound to the right, southbound to the left
Photo of the second shift in traffic on I-5
In the second traffic shift, northbound travel moves one lane to the right and southbound moves one lane to the left. This opens up space for crews to install new drainage in the project area.

Once work is done at the northbound I-5 exit to Portland Avenue – and the SR 7 and I-705 ramps are fully reopened to northbound I-5 – another shift will be put in place. Traffic on northbound I-5 will shift one lane to the right, southbound will shift one lane to the left. Doing this opens up two temporary work zones, one between northbound and southbound I-5 and another along the north side of I-5. The contractor will use this space to install drainage along southbound I-5. We expect this shift to last between 4-6 weeks, during which time the contractor will complete drainage installation.

Step Three: The final move
Photo showing the final shift in traffic on I-5
The final phase shifts southbound traffic back to its current location and expands the median work zone.

Once drainage is installed, southbound I-5 will shift back to the right, expanding the center median work zone and removing the work zone on the north side of I-5. This move sets the stage for the contractor to begin replacing the last section of 1960’s era concrete still on I-5 in Tacoma. The three northbound lanes will remain in their new (Shift Two) location until the end of the project. Once this shuffle is complete there will be no other lane shifts through the end of the project.

Wait wait, one last thing

While construction crews will be working throughout the day, planned lane closures will only occur overnight.

There will be some noticeable changes for people looking to use the northbound I-5 Portland Avenue exit during Shift One, but overall, these shifts shouldn’t feel like a major change.

Saving the best for last

When finished, the project will mark the end of the last funded piece of HOV construction on I-5 in Tacoma as part of the Tacoma/Pierce County HOV program. When that happens:
  • Southbound lanes across the Puyallup River will increase from four to five, with four general purpose lanes and one HOV lane that will continue and connect with the HOV lane to State Route 16
  • Northbound I-5 will include an additional lane at Pacific Avenue, an extra lane between the I-705 on-ramp and the Portland Avenue exit, and an HOV lane that connects HOV traffic from SR 16 into Seattle and destinations beyond.
  • A rebuilt L Street overpass that crosses over I-5
As the region continues to grow, these road improvements will better serve Tacoma travelers and residents. We ask you to stay safe traveling through the construction zone. Remember to slow down and pay attention near our work zones to keep construction crews and drivers safe.

How COVID-19 is affecting our state ferries

By Bryn Vander Stoep

It is an understatement to say that COVID-19 has greatly affected "normal life." From canceled plans to wearing masks at the grocery store, everything seems to be operating in a world of constant change.

Our ferries division is not immune to COVID-19. In late March, our total ridership bottomed off at the lowest levels we've seen since the 1960s, down more than 75% from 2019.

In response to the decreased demand, we reduced service and extended our winter sailing schedules indefinitely. We continue to encourage riders to take essential trips only, to stay in their vehicles if possible, and to physically distance from others on our ferries and at our terminals to keep everyone safe.

Now we're seeing an uptick in ridership. Ferries are a popular way to travel in the summer. But this is not a normal summer season, as we are still operating under our COVID Response Service Plan and cannot operate full "normal" service.
Like most things, COVID-19 has had a significant affect on our ferry service
as we work to adjust to new normal.

Current service levels depend on the following constraints:
  • Crew availability: More than 100 of our crewmembers are considered "high-risk" for COVID-19 and are working remotely for health and safety reasons. Before a new employee can serve as a crewmember on one of our vessels, they must go through weeks of intensive training, which includes firefighting, personal safety and survival, classroom time and job duty familiarization out in our fleet. Due to COVID-19, we were unable to conduct any of these face-to-face new deck employee orientations until June. Without enough crew to fill all the Coast Guard-mandated slots on our vessels, maintaining our current level of service has become a significant challenge.
  • Ridership: Ridership remains at historic lows and while the Governor's "Safe Start" plan is still in place, demand for transit service remains low. As more restrictions are lifted, we anticipate more riders will come back to the ferries. It is a little difficult to predict at what rate they will return, but we know that there will be more demand for service as we move through the Governor's four-phased reopening plan.
  • Vessels: The number of boats that are available also dictate our ability to provide service. Our maintenance facility was required to suspend activity for several weeks because of the Governor's "Stay Home" directive; as a result, crews were unable to conduct important maintenance on the vessels and there is now a backlog of work that needs to be completed. So without a full fleet due to a combination of planned and unplanned maintenance, we cannot operate a full schedule.
  • Funding: We cannot increase our level of service without the funding to operate that service. With decreased ridership, fare revenues have also decreased. All transportation revenue streams continue to experience significant declines as a result of the global pandemic. We're still learning how our budget will be affected in the short- and long-term.
As countless others have done, we've adjusted our way of doing business to keep people safe and healthy during this pandemic. Through it all, ferry crew members work the front line, implementing disease-prevention protocols and making sure our neighbors can safely travel across the Salish Sea each day for work, school, medical appointments and other essential trips. We know these adjustments aren't easy, and we appreciate your patience and grace as we navigate keeping travelers and staff safe.

SR 530 east of Arlington shifts to bypass so we can replace culvert for Trafton Creek

By Tom Pearce

Next week we'll shift State Route 530 traffic east of Arlington for the second part of our Schoolyard and Trafton Creek fish passage project. On Thursday, June 25, our contractor, Kiewit, will move both directions of traffic onto a single-lane bypass between Arnot Road and Kroeze Road.

People who travel this section of SR 530 during the next few months will find temporary traffic signals controlling the single-lane bypass. You'll want to allow an extra 5-10 minutes if you're traveling through the area.

This work is similar to a bypass we put in at Schoolyard Creek last summer. That bypass was shorter and allowed us to replace an old, narrow culvert under the highway. The new culvert makes it much easier for resident and migratory fish to travel up and downstream.
The new Schoolyard Creek culvert under SR 530 provides a natural creek bed, which allows
migratory and resident fish to continue farther upstream.

Trafton Creek
The bypass will be in place much longer this year because Trafton Creek is more than 40 feet below SR 530. That's a lot of material to dig up before we remove the existing culvert and replace it with a new one that's 26 feet wide.
Now Trafton Creek comes out of a pipe culvert. Fast-moving water prevents fish from traveling upstream. A new large box culvert will allow fish to get to an additional 3½ miles of habitat.

There's a big drop from the existing culvert and water travels too quickly, preventing fish from traveling upstream. With the new culvert, we will add a more natural creek bed, which will allow coho salmon, steelhead, bull and sea-run cutthroat trout to travel an additional 3½ miles of spawning and rearing areas upstream.

Importance of improving fish passage
Increasing habitat for salmon and other fish is important to the commercial and recreational fishing industries, as well as for marine life, like orcas that depend on them for food.

Improving fish passage is also something we need to do following a 2013 U.S. District Court ruling that requires us to remove culverts under state highways that are a barrier to fish passage. This ruling affects almost 1,000 culverts in western Washington. We've already done hundreds of these projects, but we need to make significant progress toward this goal during the next 10 years.

Replacing these culverts at School Yard and Trafton creeks are two significant pieces of that work.

I-405 construction resumes in June with Eastrail paving

By Victoria Miller

The I-405 Renton to Bellevue Widening and Express Toll Lanes project team has been busy preparing to start construction during the past few months. Crews will kick-off work with paving 2½ miles of the King County Eastrail, formerly the Eastside Rail Corridor, along Lake Washington between Ripley Lane North in Renton and Coal Creek Parkway Southeast in Bellevue. We expect work to wrap up by the end of this year.

More space and safer crossings coming
The new paved trail will be the widest in the region at 12 feet, with a two-foot gravel shoulder on one side, and six feet of gravel on the other side. That means that people who run, walk, and bike on the trail will have more space from others and a choice of surfaces, currently gravel only on this stretch. Crews will also install lighting at each road crossing to help protect trail-users from car traffic.

Tree removal and replanting along the trail
Widening the trail will require some tree removal. Our landscape specialists will walk the project area to identify which trees to remove and which to keep, with a goal to preserve as many trees as possible, especially the older more established trees. Our contractor then reconfirms the trees flagged for removal before work begins. We will not remove trees at the request of homeowners or others for reasons not associated with the project.

We have a robust tree-replanting policy to expand our native tree canopy while we make investments in our transportation system. We calculate the number of trees to replant based on the diameters of the existing trees' trunks, and replace trees with trunks greater than four inches in diameter with multiple trees, specifically one tree for every inch of diameter. For example, we would replace a tree with an 8-inch diameter with eight one-gallon plantings. For smaller trees, with trunks less than four inches across, we replant one tree for each tree we remove.

What to expect during construction
Starting Monday, June 29, Eastrail users will detour to the parallel Lake Washington Loop Trail between Ripley Lane North and 106th Avenue Southeast (shown in the map below). To create space for the detour, crews will narrow a 300-foot stretch of Ripley Lane North in Renton, between the Virginia Mason Athletic Center and the Lake Washington Loop Trail, to one-lane.

Most work will occur within the trail right of way during daytime shifts from Monday to Saturday each week. Trucks and equipment will enter the trail work zones via Ripley Lane North, 106th Avenue Southeast, and Lake Washington Boulevard Southeast. We plan to start construction between 106th Avenue Southeast and Newcastle Beach Park in the fall. The new trail sections will reopen in stages, with all work completed by 2020 or early 2021.

To ensure the health and safety of our crews and the community, all construction activities will follow Governor Inslee's safety guidelines for work during COVID-19.

For more information on the Eastrail construction, please visit our online open house. To stay up to date on the latest construction closure information for the project, please visit the I-405 Construction Updates webpage and the King County Construction Updates webpage.

Diverging diamond interchange: How they work

By Doug Adamson

We’ve been talking about the Marvin Road diverging diamond interchange in Lacey for quite a while but now it’s time to really get serious. The new layout is scheduled to open up this year and it’s definitely time to prepare.

While a diverging diamond interchange is intuitive for travelers, we also want everyone to get a better idea of how it works. At first glance, it may appear complicated, but  there’s nothing new to learn. You come to a stoplight and you stop. Then you follow traffic signals, signs, and lines through the interchange. Carefully designed roadway striping, arrows, and signs direct travelers. A concrete barrier in the middle of the overpass will provide access for pedestrians and bicyclists.
A key feature of this new layout is increased efficiency. Drivers make a free left turn onto the highway on-ramps without stopping at a traffic signal.

A diverging diamond interchange removes what are called conflict points. A conflict point is an area of roadway where vehicles cross, merge, or diverge. The enhanced Marvin Road interchange in Lacey will reduce the conflict points from the existing 26 to 14. This helps to improve the safety at this busy interchange.
