November 22nd winter storm response...

By guest bloggers Jeff Switzer and Bronlea Mishler

No one wants to be stuck in the middle of a gridlocked freeway in sub-freezing conditions. We apologize for the frustration and inconvenience that many commuters experienced during the snowstorm Nov. 22. Our goal is to keep the roads clear and traffic moving no matter what the weather throws at us.

On Sunday, Nov. 21, our maintenance crews pre-treated every mile of highway in King County and every on- and off-ramp with liquid anti-icer to keep ice and snow from sticking. When snow fell Monday morning, the majority of the roads remained bare and wet because of the anti-icer, and crews continued treating areas of snow and ice with either a sand/salt mix or liquid deicer.

By Monday afternoon, snowfall intensified and freezing temperatures turned standing water and slush into ice. We had 23 maintenance trucks on the road in the Seattle area treating more than 250 lane miles of freeway as commuters started filling up I-5 early to beat the impending storm. Our maintenance trucks soon got stuck in the backups and behind disabled vehicles and collisions, and that prevented them from continuing to actively salt and deice some roads. Narrow highway shoulders also prevented our trucks from getting around congested areas to continue treating icy areas, like I-5 in Tukwila.

The section of I-5 near Boeing Field and through the Duwamish Curves is elevated, which causes it to freeze more quickly when temperatures drop. There are few on- and off-ramps in this area, so drivers couldn’t exit to city streets to avoid the backups. A serious collision closed all lanes of southbound I-5 at 5:41 p.m. bringing traffic to a standstill. At the same time, the city of Seattle closed SR 99, which funneled more traffic to city streets and I-5. We warned drivers on our electronic signs that southbound I-5 was closed south of the I-90 interchange, and directed them to use I-90 and I-405 to avoid the worst congestion near Boeing Field. The freeway didn’t recover from this and other collisions until past midnight. Here are some photos of freeway conditions that evening.

Storms like the one we experienced this week certainly challenge us all in keeping the system working well. We are carefully analyzing our entire storm response, as we always do, and will make whatever adjustments are needed for the next storm.

Looking at new ways to present traveler information...

We are always looking for ways to improve the travel information we offer on our website to help you make the most informed decision and know before you go.  Recently, new technology is available that gives us new ways to display traffic conditions to you.

We'd like to show you what we have been working on internally and hope you'll  take the time to let us know what you think. On this new "alpha website," we have taken most information from our existing traffic website and put it on what we call a "slippery map." (We are calling it alpha, because we don't think it's ready for a beta just yet.) This "slippery map" is one that you can pan and zoom into, to see everything that could be happening on your route to make a truly informed travel decision before you leave.

Let us know what you think of this new website by leaving a comment in the comment area below.  We know it isn't quite finished yet, we have a few things that were left out because we want to check with you to make sure this is the direction that we should be going..

Some things we would like you to think about  while using the map
  • Does it give you a better picture of the traffic conditions on roadway?
  • Is it harder/easier to find your route home?
  • How is the navigation speed of the map?
  • Do the layers of information load quickly for you?

There are many unknowns with a site like this and our focus while you are browsing is to collect some metrics.  We need to make sure this site will handle the amount of spiking web traffic we get when it snows or have inclement weather in the Northwest. We average around 700,000 page views per day in the summer months and that number moves up to 1 million page views per day in the winter months.  When it snows in the greater Puget Sound area that number can go as high as 6 million page views per day.  We know that there is nothing more frustrating than a website that is not available when you need it and we want to make sure that no matter what direction we go our website can handle the demand.

Thanks for taking the time to check this site out and offering your feedback, we appreciate it.

Without further ado here is a link to our Alpha Traffic and Travel information website.

Heading over I-90 Snoqualmie Pass? Keep your eyes peeled for critters big or small

by guest blogger Meagan Mcfadden

The next time you head over I-90 Snoqualmie Pass, keep your eyes peeled for critters big or small. Your sightings can help identify where animals are trying to cross I-90.

You may be wondering how you get this information to the appropriate people. Well, it’s easy. The Western Transportation Institute and Conservation Northwest recently launched I-90 Wildlife Watch, a citizen-based monitoring program that invites you, the I-90 traveler, to report wildlife sightings along I-90 from North Bend to Easton. There is no animal too small to be counted; Wildlife Watch encourages you to log in all sightings, whether alive or dead. The website asks travelers to identify where they saw the animal.

This logging of animal sightings complements other wildlife monitoring work being conducted by us as part of the I-90 Snoqualmie Pass East Project. We plan to use the information logged by travelers and the other monitoring programs to determine which species of wildlife are trying to cross the interstate. This will allow us to determine where to build wildlife crossings as part of the project and to assess the ultimate effectiveness of the structures after they have been built.

Signs, signs, everywhere there's signs...

It was great to see the media coverage from the news release sent Friday (Nov. 5) reminding property owners it’s time to remove temporary political signs visible from state highways.

The signs need to be down by Friday, Nov. 12.

The folks in WSDOT’s Outdoor Advertising group are responsible for making sure Washington is in compliance with state and federal highway advertising laws. The Highway Advertising Control Act “declares that sign control adjacent to state highways is necessary to assure that information of interest to the traveling public is presented safely and effectively, and to conserve the natural beauty of our roadsides.”

Part of the state’s role in highway advertising is outlined in Washington Administrative Code (WAC) 468-66. This WAC is where you can find the regulations for temporary political signs on private property visible from state highways. First, property owners must consent. Then the signs,
  • must be removed within 10 days following the election (that’s Nov. 12, 2010)
  • can only reach a maximum size of 32 square feet in area, and
  • must comply with any local regulations.

Remember, no signs (other than those used for traffic control) are allowed within the state right-of-way. None – that includes retail, political, garage sale, etc. Why? Both safety and scenic issues. The WSDOT website provides more information about Washington’s outdoor advertising regulations.

Here are some basic clues on how to tell if a location is within a state highway right-of-way:

  • Utility poles are typically located inside the right-of-way. So no signs on the pole or between the pole and the state highway.
  • Many locations also have a fence line separating the right-of-way from private property. So again, no signs on the fence or between the fence and the state highway.

If you have question about Outdoor Advertising, contact Pat O’Leary. He can be reached at OLearyP@wsdot.wa.gov or by calling 360-705-7296. If your question is about a specific area, be prepared to provide the state route number (I-5, SR 28, US 2, US 97, etc.) and the name of the nearest intersection or approximate milepost.

So no signs in the right-of-way - none, ever. And if you do get permission to post them on private property, it's time to take them down for the season.

Reached a milestone on Flickr...10 million views

Over the weekend we reached a milestone on our Flickr account; we surpassed 10 million views!  It's quite astounding really.

Since April 2007, we've uploaded more than 12,000 photos.  We first started uploading photos in preparation for the Tacoma Narrows Bridge opening celebration.   Since then, we have found the account to be tremendously useful in telling our story.

Here's a fun compilation of some of our favorites - note the wide variety of photos:

#1 - First photo shared - April 13, 2007 Tacoma Narrows Bridge expansion joint
First Flickr Posting
The trailer needed to haul this expansion joint across the state was enormous, here is what the joint looks like in place on the bridge.

#2 -Tacoma Narrows Bridge opening celebration - July 15,2007
View from the Top
We posted photos from the bridge on the day of this event, and that event started what you see today with the regular posting of photos by our staff.  We were very excited to have Darth Vader join us:  He probably just wanted to see what successful construction looks like.

#3 - I-5 in Chehalis closed due to flooding
Aerial view of I-5 in Chehalis
I am still stunned by the power of the water in this photo. In December of 2007, I-5 in Chehalis was completely submerged for several days.


#4 - Snow Donut on North Cascades
SR 20 - Snow Donuts
This photo was published nationally and internationally. We found it amusing when the photo showed up in The Sun in the United Kingdom comparing their football coach to this snow donut.

#5 - Lewis and Clark Bridge Inspection
Award Winning Photo!
One of our employees was tagging along with a bridge construction crew in July 2008 and happened to snap this photo of the bridge inspector on the Lewis and Clark bridge.

There are others that didn't make this list that are worth mentioning, like a photo of a ferry in front of a sunset, the bunny that chased the snowplows, the pika, the bobcat, a large rock in the road, buses dangling over a free way and so many more you'll have to see for yourself.

Thanks for helping us reach such an incredible milestone.  We appreciate your views, comments and questions.  We look forward to sharing more transportation related photos with you.

Fish love our new bridge on Mount Baker Highway

It didn’t take long for fish to find their way back to Chain-up Creek once the barriers were removed.
Chain-up Creek culvert
For years, a small concrete culvert and steep drop-off made it nearly impossible for fish to return home.


But a brand new bridge along Mount Baker Highway has revived Chain-up Creek and made the journey home to native habitat easier for spawning fish.


Fish have already been spotted and photographed swimming in the creek only a month after WSDOT completed work on the new bridge and reopened the creek.


During construction, crews were careful to rebuild the creek bed. We strategically placed all the boulders, rocks and logs to mimic and foster the natural flow of a creek. And it’s paying off.

We worked all summer to shift a half-mile stretch of Mount Baker Highway away from the Nooksack River and build the new bridge at Chain-up Creek. We recently opened the new bridge, several miles east of Glacier, to traffic.

Chainup Creek flowing nicelyIt’s not just the fish who benefit from the new bridge, either. These improvements will make a big difference to drivers and residents in the area. The new bridge and rebuilt creek will reduce the risk of flood damage to the road and reduce the potential for emergency road closures. They should prevent costly emergency repairs and repeated lane closures. It’s a win-win for drivers and the environment.
