Montlake Boulevard and all ramps to SR 520 in that neighborhood closed this weekend

SEATTLE — Drivers should try to steer clear of Seattle's Montlake neighborhood this weekend as Washington State Department of Transportation (WSDOT) crews continue work on SR 520. 

Montlake Boulevard will be closed between Roanoke Street and Hamlin Street starting Friday, Aug. 27 at 10 p.m. All SR 520 on and off-ramps serving Montlake Boulevard will also be closed, according to WSDOT.

The closure will continue until Monday, Aug. 30 at 6 a.m.

WSDOT crews will be shifting Montlake Boulevard onto the new Montlake lid so they can remove the old street crossing over SR 520 and build a new, improved overpass. The work will be happening around the clock. 

"We know there are a lot of pedestrians and bicyclists that come through this area and we will have a path for them to go through, but needless to say, this will be something you'll want to avoid at all cost this weekend," said Steve Peer with WSDOT, Wednesday. 

The closure of the SR 520 ramps serving the Montlake neighborhood comes as the area also handles the ongoing closure of the SR 513 Montlake Bridge, which has been closed since Aug. 8 while it undergoes repairs. The Montlake Bridge is scheduled to reopen Sept. 3. 

The SR 520 Bridge Replacement and HOV Program is reconstructing SR 520 in phases, primarily working from east to west, WSDOT said. The changes are meant to enhance public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor, according to WSDOT.

Built in stages, the construction program's completed and planned improvements extend from I-405 in Bellevue to I-5 in Seattle. 

The Montlake portion of the SR 520 project is expected to be completed in 2023, according to WSDOT.

Work resumes over Union Bay

You may feel familiar vibrations as we vibrate piles into Lake Washington for a new eastbound SR 520 bridge. We paused some work in the lake this summer during fish migration season, but we’re back at it! Pile-driving crews may work 24 hours a day, but typical work hours are 7 a.m. to 10 p.m. Monday through Friday, and 9 a.m. to 10 p.m. on weekends and holidays. Boaters should stay alert and keep 100 feet from the bridge’s construction zone.

On a wooden platform in a construction zone above water, a crane places a large vibratory hammer on a steel column that's being placed into the ground.
Crews use a vibratory hammer to drive steel tubes into the lakebed before they install rebar and pour concrete for the new bridge’s support columns.

If you have any questions, please call our 24-hour hotline at 206-775-8885 or send us an email at [email protected] The hotline is the best way to report noise and vibration concerns and have urgent questions addressed in the moment.

Montlake Bridge reopened this morning, weekend closures on the horizon

The Montlake Bridge reopened at 5 a.m. today to all traffic following a 26-day closure to vehicles. Crews fit A LOT of work into the closure:

  • Set up scaffolding and containment around the bridge.
  • Replaced over half of the aging and cracked steel roadway panels. Panel replacement will be completed during upcoming weekend closures.
  • Added additional steel supports below the panels to increase the lifespan of the new deck.
  • Started the mechanical rehabilitation work.
  • Repaved each end of the bridge where Montlake Boulevard meets the bridge. This involved grinding down the old pavement, making necessary concrete repairs, adding waterproof material and repaving with fresh asphalt.
Crews place new metal deck panels on the Montlake Bridge.
Crews place new metal deck panels on the Montlake Bridge.
Phase 2 of the project requires closing the bridge to vehicles over five weekends, the first of which is scheduled for the busy weekend of Sept. 10-13. These closures will occur through the fall but will not conflict with Husky football home games. Our contractor has identified the following weekends to get the work done:
  • Sept. 10-13
  • Oct. 8-11
  • Oct. 22-25
  • Oct. 29-Nov. 1
  • Nov. 19-22

We will be able to maintain sidewalk access on one side of the bridge for the first two weekends but may need to restrict some access as work progresses. We’ll provide updates through these emails and on our project webpage. This is vital preservation work for a bridge that hasn’t been significantly updated since the 1990s. We greatly appreciate everyone who has stuck out these closures and switched up how they travel through the area.

SR 520 - SR 520 Closure - Montlake Project - Sept. 2020

An exclusive look at Seattle’s 520 bridge project from the construction platform

I was able to tour the 520 bridge construction zone over Lake Washington on Wednesday. I am fortunate to be the first reporter allowed onto the work platform, and I can tell you that the view was amazing.

SR 520 Bridge tolls expected to rise to make up for COVID shortfall

It only took a short walk through what used to be the north end of the arboretum, and up to the construction zone east of Montlake. The Washington Department of Transportation’s Steve Peer was my guide as we walked up to a wooden trestle and out over Lake Washington.

“We are on a work trestle, specifically built to build the eastbound lanes between the Montlake Lid and the floating bridge,” Peer said as we arrived.

This wooden trestle serves as the work platform adjacent to the where the bridge is being built. There are concrete columns rising up out of the water, surrounded by lily pads and milfoil. Ducks and geese swim along, almost oblivious to the work being done.

This is a quiet time for the project because of fish spawning nearby, so it was quite peaceful with only a handful of people working on the trestle. Peer said this design cuts down on noise pollution and environmental damage.

“It’s environmentally more friendly,” he said. “The neighbors liked it better because we weren’t doing these big drill shafting for the columns. It was really an innovative approach to construction.”

Drivers on 520 can’t see what’s happening along this trestle because it is blocked by concrete, but they have certainly noticed the giant blue cranes, all four of them, that tower above the construction. They look like “Recognizers” from the movie Tron.

They can move back and forth along the work trestle, carrying just about anything.

“Sometimes they work in pairs and sometimes they work alone,” Peer said. “What they do is the heavy lifting over the construction. They are just working from above instead of, maybe traditionally, a lot of bridges get built from below.”

Montlake Bridge opens after month-long closure, more closures still ahead

It will take until 2024 before this new eastbound bridge connecting Montlake and the floating bridge opens to the public.

“When done, it will look, from the air, just like a twin of the westbound lanes,” Peer said.

The new bridge and the complete 3-acre Montlake lid over 520 will open about the same time in 2024.

Here’s what’s coming up next for the lid: Montlake Boulevard drivers are getting used to the new configuration. They were just moved onto a portion of the lid this month.

Workers are getting ready to move the westbound exits to Montlake and Lake Washington Boulevard onto the new lid. Once that’s done early next year, workers will begin demolishing the ramp that connected that exit to Lake Washington Boulevard. They will also start taking down the old Montlake Boulevard overpass.

The lid will then be extended to the east and the west to take up that space. Eventually, there will be a 3-acre lid, complete with a new transit center. The state is also building a bike and pedestrian bridge to complete the trail across the lake.

Current News

Construction begins on a reversible bus/carpool lane between SR 520 and South Lake Union

Construction is now underway on a reversible bus and carpool connection between SR 520 and I-5's Mercer Street interchange. The SR 520/I-5 Express Lanes Connection Project will provide faster, more reliable bus and carpool travel between the Eastside and Seattle's bustling South Lake Union neighborhood. This blog article and video provide more information on this project. 

Moving forward on a new eastbound bridge over Union Bay

Two rows of concrete pillars that will support a new eastbound SR 520 bridge over Seattle's Union Bay rise from the water. To the left is a parallel bridge with vehicles on it.

With the old, 1960s-era SR 520 west approach bridge over Union Bay now largely removed, our Montlake Project crews are focused on building its eastbound replacement, as shown in this mid-September photo. The two rows of fluted concrete columns rising from the water will help support a seismically resilient, three-lane bridge for eastbound traffic. The 1.2-mile-long bridge will carry traffic from Montlake to the SR 520 floating bridge. Once crews complete the new eastbound bridge, they will remove the temporary work platforms flanking both sides of the columns. After the new bridge opens, expected in 2023, the north span (at left) will revert back to a westbound-only bridge. You can view more SR 520 photos in our Flickr collection.

Montlake Boulevard takes a new path

Aerial photo showing Montlake Boulevard before and after traffic lanes were shifted onto a freeway lid over SR 520 that is under construction.

Montlake Boulevard no longer follows a fairly straight line across SR 520, as was the case in the July photo at left. Instead, the busy arterial now curves over the highway (in photo at right) atop the center section of a new freeway lid that's under construction in Montlake. The shifted lanes will allow crews to remove the old overpass, extend the lid westward, and build a new, improved Montlake Boulevard crossing over the highway. A similar process will begin soon with the 24th Avenue East overpass at the east end of the Montlake lid. When completed, the three-acre lid will feature a regional transit hub, landscaped open space, and bike-pedestrian connections. Our crews expect to complete the SR 520 Montlake Project in 2023.

Program overview

The SR 520 Bridge Replacement and HOV Program is enhancing public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor. Built in stages, the construction program's completed and planned improvements extend from I-405 in Bellevue to I-5 in Seattle.
