SR 520 Bridge Replacement and HOV Program - News and updates

Jan. 23, 2020 | News of the week

In this update:

Sidewalk and East North Street closures begin next week

As early as next Monday, Jan. 27, crews will begin work on an access pit at the corner of East North Street and Montlake Boulevard. This work requires a closure of a portion of East North Street and sidewalk closures along Montlake and Lake Washington boulevards. These closures will be in place 24 hours a day for approximately two weeks. Local residents will have access to their homes via 24th Avenue East. For your safety, please follow the signed detour routes. 

The map below shows the upcoming bicycle and pedestrian detour route.

This closure is the first of several intermittent closures crews will implement to replace a 54-inch-diameter city water line that runs beneath the highway. The water-line installation work will take place in stages, requiring periodic detours throughout 2020 and potentially into 2021.

Good news neighbors and travelers! Crews were able to wrap up this week’s nighttime work ahead of schedule, and have canceled two planned nights of work near the westbound Montlake Boulevard off-ramp. While some work remains in this area, crews will finish it during the day to reduce effects to neighbors and travelers.

Heads up travelers – crews working along the highway

If you’re driving across the SR 520 bridge over the next few months, you may notice crews working closer to the roadway a bit east of Montlake. Crews are driving piles (think support columns) to build a temporary work bridge that will be used to remove and replace the old eastbound bridge. As part of pile driving activities, crews will use a crane and other large pieces of equipment that will be visible from the highway. During this time (and at all times, of course!) for your safety, stay focused and pay attention while you travel through this area.

Reaching out across the bridge – thanks to those who joined us in Medina last night!

Thanks to all who visited SR 520 Montlake Project staff at Medina City Hall last night! We talked with Medina neighbors and City Councilmembers about the Montlake Project design and construction. It was great to hear from our neighbors on the Eastside and get their perspective on topics such as the Montlake lid and eastbound SR 520 on-ramps. Thank you to the city of Medina for hosting us!

So long, girder! Eastbound bridge removal continues

It’s been a busy start to the year on the Montlake Project as crews continue to remove the old eastbound lanes between Montlake and the floating bridge. Crews are making big (some might say “oversize!”) progress removing sections of the bridge deck and the support girders underneath. Thanks to our construction cameras, you can even follow along at home – take a look at camera #2 for the best view of bridge removal!

Upcoming business opportunity for market or food service in Montlake neighborhood

Are you interested in opening a small market or mobile business to serve the Montlake neighborhood during Montlake Project construction? The Washington State Department of Transportation wants to hear from you! WSDOT is providing an opportunity for a vendor to establish and operate a small community market or mobile food service in the area of the former Montlake Market in 2020.

For many years, the Montlake Market served the Montlake neighborhood and travelers passing through the busy interchange. In hopes of offering a reliable, community-focused service in place of the market, this unique opportunity is now available.

Thank you to the nearly 500 individuals who recently participated in WSDOT’s community survey and provided feedback regarding the potential for a temporary service. The survey responses revealed community support for a temporary market/food service and confirmed that many Montlake residents would like to see food services continued in the Montlake neighborhood.

A full Request for Proposal is available online at the WSDOT Ad & Award site. The packet provides more information about the opportunity, proposal requirements, a submission form, and results from the recent community survey that showed significant support for a temporary market/food service.

An informational meeting will be held to provide additional details to interested parties:

  • Date: Tuesday, Jan. 28
  • Time: 3 to 4 p.m.
  • Location: Montlake Project Information Center, 2209 E. North St.
  • RSVP: All proposers interested in attending the informational meeting must RSVP by email no later than 5 p.m. Wednesday, Jan. 22. Please send your name and number of attendees to
