Montlake Bridge closed to vehicles, Aug. 9 to Sept. 3

By Joe Calabro

Back in March we gave you the heads-up about some serious work coming to Seattle's Montlake Bridge. As July draws to a close, that work is ready to get going with an almost-month-long closure.

Phase 1: 26-day closure to motor vehicles in August

From Aug. 9 to the morning of Sept. 3, the Montlake Bridge will be closed around-the-clock to motor vehicle traffic. If you typically walk or bicycle over the bridge, fret not! The sidewalks over the Montlake Cut will remain open as crews work.

Why don’t we keep a lane or two open for cars and buses? Safety. During this phase of work, crews will add extra support beams and remove and replace metal grid deck panels. This means at any time there could be a gaping hole in the bridge’s surface. Add crews and equipment into the equation, and it makes the most sense, safety-wise, to keep the bridge closed.

The new metal panels are ready to be installed on the Montlake Bridge, replacing the existing 23-year-old deck.

Since this is a movable bridge, maintaining boat traffic through the Montlake Cut is essential. Boaters that require the bridge to be raised can request ‘single-leaf’ openings. This means one side of the bridge will open upon request. Full bridge openings require 24-hour notice to the bridge operator.

Single-leaf bridge openings will allow boat access without disrupting work on the other side of the bridge.

Plan ahead and change how you move

This is a big deal! The Montlake Bridge is an important and well-used connection between Montlake, the University District and beyond. The bridge carries around 60,000 vehicles per day. With it closed, those travelers will need to go a different way. We expect to see some backups on city streets around Montlake Boulevard, but the length of those delays depends on how well folks can adjust:

• Walk or bike across the bridge! Take advantage of the open sidewalks and sunny weather, even if it’s just once or twice per week. Who knows, you might just have a new routine on your hands.
• Let King County Metro be your chauffeur. Our transit friends will have reroutes ready to go for this closure. Ride with them and read, catch up on the news, get some work done, listen to Olivia Rodrigo – whatever.
• Get a lift with Link light rail. Catch the Link from the University of Washington Station to Capitol Hill and beyond, or vice versa.
• Carpool. Find a friend, coworker or family member to make riding the detour easier. Just remember to check traffic before you go and plan for delays.

The bridge sidewalks will stay open through the 26-day closure to vehicles. A sunny August day is a great time to turn a driving trip into a stroll across the bridge.

Two birds, one closure

With the Montlake Bridge closed through much of August, traffic on Montlake Boulevard will be reduced as travelers use other routes to head north and south. The neighboring SR 520 Montlake Project will take advantage, doing cleanup work around the former Montlake Market and gas station. Expect Montlake Boulevard at SR 520 to be reduced to a single lane in each direction during most of August. By bundling all this work into a single timeframe, we’re reducing the number of disruptions to the community.

Mountlake Boulevard at SR 520 will be reduced to one lane for most of August.

Weekend closures this fall

Once the deck is replaced in early September, crews will begin rehabilitating the bridge's mechanical systems. This work will take up to five weekends this fall. During those weekends, the sidewalks and road will be closed across the Montlake Cut. Boat access will not be affected. Be sure to check our webpage for any updates to this schedule.

An alert driver and Hood Canal Bridge crew help save tiny kitten

By Doug Adamson

Rescuing and providing aid to stranded boaters near the State Route 104 Hood Canal Bridge is something our bridge crews train for and have experience in. This past month, the crew performed a rescue that will make animal lovers pause, or in this case, paws.

On July 25, a 911 call was routed to the bridge crew after a driver who was stopped on the bridge while the drawspan was open for a boat crossing heard repeated cries from a tiny animal. She shockingly saw a kitten precariously clinging to an air vent about 25 feet below the bridge deck.

An alert driver and our Hood Canal Bridge crew rescued this stray kitten from the bridge.

It's not known how long the kitten was there or how the poor animal got there.

Hood Canal Bridge supervisor Paul Gahr first figured the noises were the high-pitched calls of a pigeon guillemot, a bird often found around the bridge. After a search didn't find anything unusual, something told Gahr to look again.

The black kitten was hard to see as it was clinging against the blackened backdrop created by generators. Scared and alone, the little animal jumped, falling about 20 feet to an area accessible only to crew members.

Hood Canal Bridge crew member Virginia Smith shows where the tiny kitten was stuck and rescued from (see red arrow) on the bridge.

"I thought the worst, but the kitten didn't even have a scratch," Gahr said.

Hood Canal Bridge crew member Virginia Smith heard about the situation. Smith brought in a cat carrier from home which helped comfort and contain the kitten.

An examination by a nearby Port Ludlow veterinarian revealed the animal somehow wasn't hurt despite falling 25 feet and later another 20 feet.

The rescued kitten is now in the home of the driver who originally reported hearing it on the bridge.

Gahr called back the driver who first spotted the kitten in distress.

"The driver who spotted the kitten was thrilled it was OK, and then agreed to give the 8-week-old kitten a permanent home," Gahr said.

We didn't catch the name given to the kitten, but "Lucky" seems appropriate.

New ramp meter alleviates traffic congestion, improves safety at SR 167 to northbound I-405

By Jordan Longacre

A recently installed ramp meter on State Route 167 where drivers merge onto northbound Interstate 405 in Renton will go live for the first time on Tuesday, July 27. Anyone who has merged onto northbound I-405 from SR 167 has likely been caught in heavy traffic or even experienced a collision at this location. The SR 167 ramp meter will help alleviate congestion and incidents and prevent free-flowing vehicles from hitting a dead-stop at the I-405 merge point, improving efficiency and safety for drivers.

The new ramp meter will regulate traffic during the peak morning commute from 6 a.m. to noon and intermittently during the afternoon in response to heavier traffic. This traffic change is part of an adaptive freeway metering system that automatically activates and adjusts each ramp meter based on current conditions. Additionally, our traffic engineers will monitor the meter timing and adjust as needed to ensure the best traffic flow.

Why do we meter?
Without ramp meters, vehicles entering the freeway merge together in tightly packed groups, which can cause drivers on the highway to slow down or even stop as they merge. This results in slower speeds, both on the freeway and on the ramp, quickly contributing stop-and-go conditions. By pacing the vehicles evenly at a controlled rate, the merge is much smoother.

In the case of SR 167 to I-405, vehicles currently go from traveling at 60 mph to a dead-stop near the merge point as they enter I-405. The meter prevents tightly spaced groups of cars from merging onto the freeway at once, which will keep I-405 flowing smoother during those times. The largest benefit of the new ramp meter will be at the beginning and the end of the peak commute times. By metering at the beginning of the commute, free flow on I-405 continues longer. Metering at the end of the commute ensures free flow returns faster, improving travel for all motorists.

How will a ramp meter be effective and efficient here?
Based on recent data collected along SR 167 and I-405, traffic along SR 167 is now exceeding 2017-2019 pre-pandemic averages and volumes along I-405 are within 10 percent of 2017-2019 pre-pandemic averages. With traffic on I-405 likely to continue increasing, the ramp meter will allow us to better manage the high traffic volumes entering I-405. If the meter can manage SR 167 now, as our analysis shows, it can manage pre-COVID volumes due to the similarity to the 2017-2019 midweek average.

• Ramp meters automatically respond to changing traffic conditions. If traffic is flowing well, then the meter is not activated. During periods when traffic flow is beginning to slow down or conditions have become congested, ramp meters are in operation and automatically adjust to move vehicles more efficiently.
• Ramp meters really show their effectiveness when it comes to managing traffic following a crash on the freeway, helping traffic recover quicker.
• The ramp meter can help delay and/or prevent congestion from extending past the SR 167/I-405 merge point.
• The SR 167 ramp meter can help alleviate and prevent free-flowing vehicles from hitting a dead-stop at the I-405 merge point.
• A portion of the ramp shoulder area will serve as an additional lane during metering periods, preventing ramp metering backups onto SR 167.
• Ramp meters are designed to help evenly pace vehicles merging onto the freeway, providing consistent gaps between vehicles, rather than multiple vehicles flooding onto the highway at once.
• Ramp meters create a steadier flow of traffic onto the highway and reduce travel times.

A look at the direct connector HOV ramp that connects SR 167 to northbound I-405 in Renton.

How does this improve safety?
Ramp meters are an effective tool used to operate state highways safely. More than half of the collisions over the past five years have occurred where SR 167 merges onto northbound I-405.

• Ramp meters improve safety by allowing one vehicle at a time to merge onto the interstate, reducing the severity and number of collisions due to merging traffic.
• Gaps between merging vehicles will make the merge easier for drivers and reduce the risk of collisions.

What should I expect as a driver?
For drivers who normally use the SR 167 to I-405 ramp, one notable change will be the addition of a 1,250-foot shoulder lane that will also be metered. The ramp meter will have two signals that will alternate green lights to cycle vehicles through at an even pace. Signs are in place indicating both lanes are available when the ramp is metered.

• Our traffic studies have shown drivers currently spend about 3 to 8 minutes on the SR 167 ramp to I-405. With the operation of the ramp meter, we expect morning commuters to experience similar delays on the ramp, while some evening commuters may experience a slight increase in ramp delays, but with the added benefit of safely merging into traffic flow on northbound I-405.
• More consistent delays on the ramp for drivers will help provide better merging conditions, reducing overall congestion in the area.

The shoulder of the SR 167/I-405 ramp will be converted to a 1,250-foot storage lane (here on the far right) to be used for peak travel times to help keep traffic moving.

Will HOV and transit be able to use the ramp meter?
Carpools, vanpools and transit traffic will be able to use the I-405 Direct Connector HOV flyover ramp that connects SR 167 to I-405 via the leftmost travel lane but can also use the metered general-purpose ramp if they choose.

• Metering the exit to I-405 would likely encourage eligible motorists to use the Direct Connector HOV flyover ramp.
• The Direct Connector HOV flyover ramp adds additional capacity (HOV, transit, emergency vehicles) and reduces traffic volume that would have been using the normal ramp in previous conditions, again alleviating traffic congestion.
• The general purpose and HOV lanes on northbound SR 167 just north of the South 180th Street interchange are excluded from the toll algorithm as the High Occupancy Toll Lane ends in this location.
• We will be monitoring traffic on the Direct Connector before and after metering begins and will make recommendations regarding enforcement.

Multiple wildfires likely to keep stretch of SR 20 closed until further notice

Update: August 9, 2021

The section of SR 20 between mileposts 165-178 reopened Monday morning at 8 a.m. so there are no current closures of the highway.  However, fire response crews continue to use the highway for staging and work, so currently there is a 35 mph reduced speed and a pilot car moving traffic between mileposts 166 and 172.

Respect traffic control
The pilot car will run during the day Monday and Tuesday while fire fighters are working.  We expect that this will cause delays so if you must use the SR 20 through this section, plan for longer than normal travel times and some slow-going.  Do not pass the pilot car or pull over in that section as this will cause safety hazards to crews and the traveling public.  The pilot car will not be in place once darkness falls, so you if you can adjust your trip times, you may avoid some delays.

Fires are still burning throughout the state – please be safe
Even with the reopening, there are still fires burning throughout the state that may affect travel and conditions can change quickly.  Keep this in mind when preparing for your trip and make sure you have plenty of water, a full tank of gas and have checked our app or travel alert map for the most current information before you head out on a trip.

Remember, secure tow chains, never toss burning materials out of your vehicle (don’t litter at all please!) and don’t pull over into tall grass while traveling to help reduce the risk of starting roadside fires. 

Update: August 3, 2021

Fires and fire response activity in the area means that the SR 20 closure will remain in place at least through this week.  Firefighters have made great strides in the containment of the Cedar Creek and Cub Creek 2 fires, but with hot, dry conditions and low visibility due to smoke, it is not yet safe to fully reopen the road. 

Closed means closed

At the moment, the closure points are between milepost 165 and 179, west of Mazama in the Methow Valley.  However, the east side closure point has changed several times and local evacuation levels have been raised and lowered over the past several days.  Air quality in the area also rates from “unhealthy” to “hazardous”.

We continue to see people who are trying to force their way through a closure sign or who are not prepared for the road closure when they reach the area.  This is a problem the crews working this fire should not have to deal with – we all want them focused on the fire and keeping themselves and nearby residents safe.  There is no local access or Forest Service detours. Cross-state travel is available on US 2 and I-90.

Still opportunities to enjoy the North Cascades

From the west you can still access as far at The Overlook on SR 20, and Diablo Lake and Ross Lake are far enough from the fires that air quality is much better.  It is still essential to be prepared for hot summer driving conditions with plenty of water, a full tank of gas and well-researched travel plans.  These fires are not the only things happening that could affect your travel plans this summer.

When will it reopen? Can’t you make an estimated guess?

The short answer is “not really.”  Our agency supports the Incident Command Team that is managing the fire response.  Everyone is eager to get the road back open and traffic flowing, and the ICT has specific goals for what conditions are needed for that to happen.  Every day we meet to get updates and coordinate our effort to reach those goals, but the fact remains that fire conditions remain hazardous and dynamic, and the priority is safety for you and the crews working out there. 

If you are trying to make plans for your late summer trip, the best thing you can do is keep checking our travel alerts map and check for updates on Facebook, the WSDOT app and this post.

By Mike Allende

As you may be aware, the Varden, Delancy and Cedar Creek fires have been burning in Okanogan County for most of July. This has led to the closure of a stretch of the SR 20 North Cascades Highway, currently now stretching from mileposts 165 to 185, west of Mazama in the Methow Valley. Emergency responders requested the closure for safety and to allow them to stage equipment to battle the fires. The closure also is helping evacuations in the area.

Despite the incredible efforts of the firefighters, the fires continue to expand and emergency personnel now advise us that the highway closure will likely be in place at least through July and potentially longer.

We know road closures are frustrating and we don’t close them unless it’s necessary for safety. In this case, the requests of those tackling these dangerous conditions along with the related evacuations – including Okanogan Fire District and the National Forest Service – make clear that this closure is needed for the safety of everyone.

Three large wildfires burning in Okanogan County forced the closure of a stretch of the SR 20 North Cascades Highway west of Mazama.

We also recognize that the North Cascades Highway is a popular destination this time of year for travel between the beautiful Skagit and Methow valleys. The good news is, some of the most popular sites are still accessible, it just may take a little longer to get there.

OK, how do I get there?

This time of year, many people travel from the west side to Winthrop, Twisp Mazama and other areas that are easily reached once the SR 20 North Cascades Highway reopens from its winter closure in the spring. And while that highway does provide a convenient link between west and east, it’s not the only way to reach the Methow.

Typically, it takes about three hours or so to go from Seattle to Winthrop using SR 20. Getting there with that highway closed will add about 1½ hours to your trip. The most common way is:

·         I-90 eastbound for about 82 miles to exit 85

·         Take US 970 northbound toward Wenatchee

·         Continue on US 970/SR 10 for about 10 miles. This turns into US 97, which you’ll stay on for about 35 miles northbound

·         Merge onto eastbound US 2/northbound US 97 and US 97 north will take you into Twisp/Winthrop.

Alternatively, you could take US 2 over Stevens Pass through Leavenworth:

·         Take I-5 northbound to Exit 194/eastbound US 2 in Everett

·         Continue on US 2 for 107 miles, over Stevens Pass and through Leavenworth to Wenatchee

·         Take the US 2/US 97 north ramp to junction of US 2/97 and SR 28 in East Wenatchee and go left onto US 2/US 97 toward Orondo/Okanogan

·         Continue 57 miles toward junction of US 97/SR 153 south of Pateros and take a left onto SR 153 west to Winthrop. Continue for 40 miles to Winthrop.

Be sure to consult your favorite mapping app as it will help guide you where you need to go.

What’s open on SR 20?

The most popular destinations on SR 20 tend to be Diablo Lake and the Washington Pass overlook. They are truly beautiful locations with amazing views. The good news is that both are still open and accessible as they are west of the closure. You just won’t be able to go much further east than Washington Pass, including down into the Methow Valley. Also note that the North Cascades Highway is extremely popular and like most of the most popular recreation destinations in our state, it can get very crowded. Be sure to have backup plans if your preferred spot is full and never park illegally on the sides of the highway.

Remember that services are limited as you head into the mountains.  Gas stations, public rest areas, cell service and turn around points become increasingly limited heading east into Rainy Pass and Washington Pass.  Running out of gas or otherwise becoming stranded will make for a much longer, more stressful trip.

A look at where the road closure is compared to Washington Pass and Diablo Lake. Note that the unpredictability of fire means the closure points can move with little notice.

But is it safe?

If a highway isn’t safe, we would close it until it was. That said, there are fires burning east of Washington Pass and fires can be unpredictable. They can also lead to fast-changing conditions, road closures and delays. We encourage anyone traveling to areas where there is active fire activity to check with local emergency responders to see what the threat level is and also encourage people to research what the air condition is before they head to their destination.

You can also download our app for road updates, call the 511 travel information number and check our travel alerts page for more information.

Be prepared

Wherever you’re heading this time of year – but especially if you’re headed to areas with active fires – be sure you and your vehicle are prepared. As we mentioned, fires are unpredictable so road closures and delays can happen with little warning. Be sure you have plenty of gas, water, food, cell phone charger and other items you might need in an emergency. And be sure your vehicle is well maintained.

Those who are traveling in the area of active fires should be prepared for potential road closures or delays as they can happen quickly.

Closed means closed

It still amazes us that this happens, but we continue to get reports from those staffing the road closures that people are attempting to go around the closures. So to be clear:

·         There are no nearby alternate routes around the closure. There are no Forest Service roads or other side roads open that allow access. It’s closed. Closed.  You can’t go through. Closed.

·         Trying to get through a closed road puts you and others in the area at risk. There are literally fires burning nearby. You should be avoiding that, not driving into it.

·         If you go through a closure and get stuck, emergency responders including firefighters have to go save you. That puts them at even more risk and also takes them away from what they should be doing, which is fighting the fires that led to the closure.

We understand that there’s never a good time to close a road, especially a very popular summertime route like SR 20. We would love to have this route open, but safety of those responding to the fires and for the public is always No. 1. So until we get the all clear from the emergency responders battling to keep us all safe, the road must remain closed and we appreciate your understanding and cooperation.

With most paving complete, Revive I-5 shifts to expansion joints

Update: Thursday, July 22
The next scheduled Revive I-5 weekend closure - July 30 to Aug. 2 - has been canceled. Be sure to check the project website linked below for updates on the schedule.

---

By Tom Pearce

This past weekend our contractor finished most grinding and paving portions of our Revive I-5 project on the southbound freeway between I-90 and Spokane Street in Seattle. Crews began by grinding I-5 to smooth the surface during overnight shifts. During two weekends when lanes were reduced, they repaved a thin layer of polyester concrete, which is more durable than regular concrete.

We have repaved about 1¼ miles of all lanes of this section of southbound I-5, which has anywhere from three to five lanes. With the paving mostly finished, now we’ll turn our attention to expansion joints in the same section of freeway. 

No easy task replacing 56 expansion joints

This part of the freeway is built on piers like a bridge, so it has 40 expansion joints that allow it to expand and contract with weather changes. If you drive this section very often, you know the joints need to be replaced. In addition to the occasional bump or metallic clunking sound you may encounter, we’ve had several break in the past few months, requiring emergency repairs on weekday mornings or afternoons. That creates unplanned backups and delays.

When an expansion joint breaks, we have to repair it right away regardless of traffic and time of day.

In addition to those on the main section of the highway, we have 16 other expansion joints to replace on ramps that serve this part of the freeway. Replacing just half of a joint takes an entire weekend. We’ll do several halves during each closure, but it’s going to take at least 14 more weekends between now and summer 2022 to replace all of them.

Why so long?

Yes, that makes for a long project, but there are several factors. First is events in Seattle. When a weekend sporting event or concert brings an additional 35,000 to 65,000 people to the area, it’s very difficult to schedule work.

Then there’s the material – when we replace these expansion joints, we’ll use the more durable polyester concrete. But that limits working conditions – it needs to be more than 50 degrees Fahrenheit and completely dry to pave this type of concrete.

Polyester concrete is more durable but it requires dry weather and moderate temperatures.

We also need to plan ahead for this work to be sure we can get the materials we need and let you know we’re going to work. The weather, materials and notification time pretty much eliminate working during the winter as well as much of the spring and fall.

Stay looped in to the project schedule by checking the website. You can find info about the next weekend closure – July 30 to Aug. 2 – on the project page.

I’m always looking for a silver lining. For this project, while we’ll be working a lot of weekends, we’re going to wrap up most of the weeknight work by early August. A lot of people think the freeway is empty at night. I can guarantee you it is not – when night work creates backups, I hear from people who drive then. Besides, it’s not practical to replace expansion joints during overnight shifts – it would take much longer and final product would not be as strong.

We know that weekend lane reductions are hard on a lot of people. At least this way, you can plan around the work, unlike when a joint suddenly breaks and we need to do an emergency repair. Thanks for your patience!

Buckle up: Construction starts this summer on the SR 520/I-5 Express Lanes Connection Project

By Amanda Christopher

Despite all the negative effects of the COVID-19 pandemic, our largest county, King, still added 34,000 new residents in 2020. By 2050, the central Puget Sound region is predicted to add 1.8 million more people and another 1.2 million jobs, according to the Puget Sound Regional Council's VISION 2050 report.

The region's population and employment boom has been especially pronounced in Seattle's South Lake Union neighborhood. At the same time, the Eastside's technology-driven cities continue to grow steadily. This ongoing growth underscores the importance of a safe, reliable transit/HOV link between Seattle and the Eastside via State Route 520.

To that end, we're beginning construction of a new project this summer in Seattle – the SR 520/I-5 Express Lanes Connection Project. This project will connect SR 520's new transit/HOV system to the I-5 express lanes, creating a direct bus and carpool connection between the Eastside, South Lake Union and downtown Seattle.

The work is part of our overall "Rest of the West" program – a series of safety and mobility enhancements along the SR 520 corridor in Seattle. Construction on the SR 520/I-5 Connection project is slated to begin soon and take about three years to complete. The Legislature's 2015 Connecting Washington transportation legislation provides the project's funding.

This project will deliver several key benefits to improve travel speed and reliability:

1. A new ramp between SR 520 and the I-5 express lanes for buses and carpools.
2. A new, reversible transit/HOV lane along the I-5 express lanes, running between I-5's interchanges with SR 520 and Mercer Street. (Traffic moves southbound in these lanes during the weekday morning commute, and northbound during the afternoon/evening commute.)
3. A reconfigured Mercer Street on-/off-ramp to and from the I-5 express lanes for buses and carpools.

A look at the key features of the I-5/SR 520 connections project

Building for the future

Although the COVID-19 pandemic caused a significant decrease in traffic volumes and transit ridership throughout the state – including on SR 520 and I-5 – we're building for the future. The improvements from this project will serve the region for at least the next 75 years as our population and economy continue to grow. Already we're beginning to see traffic and transit volumes rebound as businesses reopen and workers begin returning to the office.

Overall, the $4.5 billion SR 520 Program is reconstructing the highway from I-405 in Bellevue to I-5 in Seattle. When our remaining SR 520 improvements in Seattle are complete, we expect about a 30-minute reduction in peak-period travel time for buses and carpools between the Eastside and South Lake Union. We also expect to see an increase in additional daily transit trips/riders. We're working closely with our transit agency partners at Sound Transit and King County Metro, as well as the city of Seattle, to confirm future bus service and routes on the highway and into South Lake Union.

A couple other important notes:

• The new direct-access ramp and reversible express lane initially will open to buses only; carpools won't be able to use the new ramp until the completion of the Portage Bay Bridge and Roanoke Lid Project. This phased approach will help provide safer merges for buses while the Portage Bay Bridge replacement is under construction.
• While the SR 520/I-5 connection will improve travel for buses and carpools, this project does not address the "Mercer Weave" for motorists crossing several general-purpose lanes of traffic when merging from SR 520 onto southbound I-5 and then exiting at Mercer Street.
• Untangling the "Mercer Weave" would require a separate, legislatively directed I-5 project in the future that is not currently planned or funded.

What to expect during construction
As with any major construction project, while we're excited for the end result, we know the work will present some challenges and trade-offs for the community. Nearby neighbors may experience increased noise, truck traffic and nighttime lighting. And travelers may see delays, detours and temporary road closures as crews work to safely and quickly build this new connection.

Because this project is taking place right in the middle of two major highways – I-5 and SR 520 – much of the work must occur at night. This is for a few key reasons:

• Working at night with less traffic will provide a safer work environment both for the contractor and for the traveling public.
• Night work will avoid disruptions to daytime traffic on SR 520 and I-5, two vital routes for weekday commuters.
• Working at night allows us to shorten the overall project duration, which reduces the length of time we're affecting the surrounding communities and reduces construction costs to taxpayers.

We recognize that working at night can be especially disruptive for neighborhoods closest to the work zone. As part of this project, we were granted a project-long nighttime noise variance from the city of Seattle. The variance lays out specific measures our contractor must and will take to mitigate effects on nearby residents, including advanced notice of noisy work, limiting impact work (such as jackhammering and pile driving) at night, and other adjustments such as not using compression brakes or letting equipment idle. You can read more about the variance by visiting the Seattle Services Portal, project number 6733975-NV.

In addition to this noise variance, we developed a Community Construction Management Plan that details the actions our contractor crews will follow to limit the effects of construction on nearby neighbors and travelers. This is a living document that can be updated periodically based on community feedback.

The SR 520/I-5 project will add a new connection between two of the Puget Sound area's busiest highways.

In addition to noise and other effects such as dust and added lighting, we know that a major project like this will bring delays and highway closures for drivers in the area. This may include temporary off-ramp detours, closing the I-5 express lanes earlier in the evening, and opening the express lanes later in the morning. As with any major traffic effect, we'll be sure to communicate these closures in advance so drivers can make alternate plans.

Staying informed
There are a number of ways to stay informed during SR 520 construction:

• Call our 24-hour construction hotline (206-316-2559) with pressing questions or concerns.
• Email SR 520 staff with your questions about the project or construction activities.
• Visit the SR 520 Construction Corner for the most up-to-date information on closures and construction effects.
• Visit the SR 520/I-5 Express Lanes Connection Project website to find general project information.

Much-needed southbound I-5 work resumes weekend of July 17-18

By Tom Pearce

As we move into the peak of summer, you're going to see more weekend work that affects I-5 and highways around the Puget Sound area. We need good weather for a lot of the work we do and as the old saying goes, you've gotta make hay while the sun shines.

One of the biggest projects we have is on southbound I-5 between I-90 and Spokane Street, part of our Revive I-5 effort. The weekend of July 17-18, we'll reduce southbound I-5 to two lanes on Saturday and only one lane on Sunday. In addition, we'll close the collector-distributor ramp to southbound I-5. You'll still be able to get into the collector-distributor, but you'll have to exit to Dearborn, I-90, Fourth Avenue South or Airport Way.

Finally, the mainline I-5 off-ramps to Forest Street/Sixth Avenue and Spokane Street/Columbian Way will also be closed.

The off-ramps from the I-5 collector-distributor to SODO will be open during the weekend work, but the I-90 and collector-distributor ramps to southbound I-5 will be closed.

We try to schedule these weekends to avoid events that will draw huge crowds, but we can't avoid everything. For example, Seattle is marking the end of COVID restrictions with a "Welcome Back" celebration in the Chinatown International District July 17-18. We may be working on I-5, but you'll still be able to get to this event and others in the city.

There are all kinds of public transportation options in Seattle. Cycling is very popular and the city has many miles of bike lanes. If you feel the need to drive, consider carpooling and allow extra time.

Why so many closures?
This Revive I-5 project will require at least 16 weekend-long lane reductions between now and fall 2022 to finish the needed work. On July 17-18 our contractor, CA Carey, will finish the major paving work on a 1¼-mile section of I-5 between I-90 and Spokane Street.

During the rest of the closures, we'll replace 40 expansion joints on the freeway as well as 16 others on the ramps that serve I-5 in this area.

In the past few months our crews have had to make several emergency expansion
joint repairs in the middle of the day on I-5.

If you drive this area frequently, you've probably seen our maintenance crews out doing emergency repairs on broken expansion joints. We've had to repair about seven of these since the start of spring. And they seem to break at the most inconvenient times – the middle of the day, or in the case of the most recent one, during peak afternoon traffic.

Repairing these joints during scheduled closures can be tough on people who need to travel, but scheduling them allows many people to adjust their travel plans and reduces the number of vehicles on that section of highway.

Thanks for your patience. We have a lot of work to do on I-5. With good planning, we'll finish it and you'll get to your destination.
