SR 520 Bridge Replacement and HOV Program - News and updates

Sept. 6, 2019 | Rest of the West news

Here’s what you’ll find below:

Reminder: westbound SR 520 off-ramps to Montlake and SR 520 Trail closed this weekend

Montlake Blvd off-ramp will stay open between 12:30 and 10 p.m. for Husky game day

If you’re traveling on SR 520 this weekend, please be prepared for travel delays and westbound off-ramp closures in Montlake. Crews will use the weekend closures to build a new, temporary off-ramp to Montlake Boulevard that travelers will use for much of the four-year Montlake Project.

Crews will work around the clock Sept. 13-16, condensing their work to minimize disruptions for local residents and travelers. While closing the westbound off-ramps to Montlake Boulevard and Lake Washington Boulevard can be inconvenient for a weekend, it allows crews to complete their work more quickly and efficiently, averting what would otherwise be many overnight sessions of noisy work. Whenever possible, the noisiest construction activities this weekend will be done during daytime hours.

Highlights of what you need to know for the weekend

  • From 11 p.m. Friday, Sept. 13, to 5 a.m. Monday, Sept. 16, the westbound SR 520 off-ramps to Montlake and Lake Washington boulevards and the SR 520 Trail across Lake Washington will be closed.
  • To accommodate Husky football game-day travelers on Saturday, Sept. 14, the westbound off-ramps will be open before, during and after the game (see details below).
  • The cross-lake SR 520 Trail will be open only as an out-and-back option from the Eastside to the west end of the floating bridge. Bicyclists and pedestrians will not be able to cross Lake Washington to Seattle.
  • Bicycle and pedestrian access across the 24th Avenue East overpass will close Friday night, Sept. 13, and remain closed for the duration of the Montlake Project. A detour route will be open along Montlake Boulevard.

What Husky game-day travelers and tailgaters can expect on Saturday, Sept. 14

  • The Montlake Boulevard/University of Washington off-ramp will be open from 12:30 p.m. until two hours after the game ends (approximately 10 p.m.).
  • The Lake Washington Boulevard off-ramp will be open from 2:30 p.m. until two hours after the game ends.
  • Outside of these times, the westbound off-ramps will be closed. Traffic headed to northeast Seattle will be detoured to Northeast 45th Street via northbound I-5.
  • All eastbound SR 520 ramps, as well as the westbound on-ramp from Montlake Boulevard, will be open this weekend.
  • The SR 520 Trail will remain closed across Lake Washington during this time. Trail users can catch a bus from the Evergreen Point Road station to reach Montlake while the off-ramps are open.
  • Bicyclists and pedestrians traveling from the south of SR 520 will detour onto Montlake Boulevard to cross SR 520, as the 24th Avenue East overpass crossing closes this weekend for the duration of Montlake Project construction.
  • For more information about parking, and public and alternative transportation, see the University of Washington’s Football Transportation webpage.
  • Riding the bus? Be sure to visit King County Metro’s Alerts & Updates page for more information.

What to expect following the weekend: Don’t miss your exit Monday morning!

  • During the ramp closures, traffic headed to northeast Seattle will be detoured to Northeast 45th Street via northbound I-5.
  • On Monday, Sept. 16, westbound drivers exiting to Montlake Boulevard will use the new, temporary off-ramp’s two right lanes.
  • This is a change from current conditions, where drivers use the off-ramp’s left lane to access Montlake Boulevard. Starting Monday, the ramp’s left lane will connect vehicles to Lake Washington Boulevard.
  • Bus riders should visit King County Metro’s Alerts & Updates page for more information about transit service this weekend.

What to expect for bicyclists and pedestrians

  • For SR 520 Trail users on the Eastside during the weekend closure, the trail will be open to approximately halfway across the Lake Washington as an out-and-back option; users will not be able to travel all the way to Seattle.
  • Access across the 24th Avenue East overpass will close Friday night, Sept. 13, and remain closed for the duration of the project. When the project is complete, the route will reopen over the new Montlake lid. During project construction, detour routes will be available along Montlake Boulevard.
  • Within the next few weeks, a temporary connection will open from the SR 520 Trail to Montlake Boulevard just north of the Montlake Boulevard off-ramp. Later this year, we’ll open a separate north-south route for bicyclists and pedestrians that passes under SR 520 east of 24th Avenue.

As always, if you have any questions about this work, you can call the 24-hour Montlake Project construction hotline at 206-775-8885.

Additionally, all of our construction cameras are online! You can now follow along as construction progresses. New pictures are taken every 30 minutes, and you can browse through previous photos and time lapses as well.

Plan ahead: Sept. 21-22 weekend closure of the eastbound SR 520 Arboretum on-ramp

In preparation for construction of a new eastbound SR 520 bridge over Union Bay, crews will be doing soil-sampling where the eastbound on-ramp through the Arboretum joins the SR 520 mainline. To ensure the safety of crews and the traveling public, the on-ramp must be closed from 11 p.m. Friday, Sept. 20, to 5 a.m. Monday, Sept. 23.

Crews will work day and night through the weekend to complete the work as quickly as possible and minimize traffic disruptions. During the ramp closure, drivers can use the eastbound on-ramp at Montlake Boulevard.
