Walk the new pedestrian bridge over SR 520 on a clear evening and you'll do what everyone does the first time: follow the wide paved path expecting it to drop you into the Arboretum. It doesn't. The trail ends at a flashing beacon crosswalk across Lake Washington Boulevard at E Roanoke Street, and from there you're on your own to find the old stone footbridge at E Lynn Street or the Lake Washington Loop route at 25th Ave E. The bridge itself is genuinely well built. It just doesn't go where the renderings implied it would.
That gap between the announcement and the walk is the story of Montlake right now. WSDOT's own project page states plainly that the Montlake Project "is complete." For a resident who has lived through years of cones, detours, and rerouted commutes, that word deserves a second look before you take it at face value.
What the State Actually Finished
The scope of the completed work is real and it's substantial. The project delivered a new eastbound SR 520 bridge over Union Bay, a three-acre landscaped lid over the highway with room for regional transit stops, and a separate bicycle and pedestrian bridge connecting the lid to points east. KIRO7 reported the interchange work cost $486 million and included a 14-foot-wide paved trail that opened to the public in December 2024 after years of construction. That part of the story checks out. The complication is everything the word "complete" is being asked to absorb along with it.
A Bridge That Ends at a Crosswalk
The disconnect at Roanoke isn't a rumor. Seattle Bike Blog documented it within weeks of the bridge opening, noting that the new crossing "doesn't actually connect to the Arboretum" and instead lands walkers and cyclists at that signal-controlled crosswalk. For NOAA Fisheries employees and anyone else who used to reach the Bill Dawson Trail from the west side of Montlake Boulevard, the old connection is gone. They now have to cross the widened boulevard and pass underneath it again through a new tunnel to get where the old sidewalk used to take them directly.
None of this makes the bridge useless. It makes it a different kind of useful than the connectivity language suggested, and if you're routing a bike commute or a dog walk through this corner of the neighborhood for the first time since the ribbon cutting, it's worth testing the route before you commit to it.
The Park That's Still Not a Park
Here's the piece that surprises longtime residents most. East Montlake Park, the waterfront park along the Montlake Cut with its totem pole and observation deck, was permanently closed in 2019 in preparation for the highway project. The city's own parks page still lists it as closed today. Seattle Bike Blog's reporting on the area notes that the old construction staging site nearby is slated to eventually become a new 22-acre park called the North Entrance Project, but that follow-on project remains unfunded, so there's no real timeline for when any of this fencing comes down.
So the neighborhood picked up a new three-acre lid park while a longtime waterfront park just up the shoreline stays closed with no committed reopening date. That's the trade nobody put on a poster.
| What the announcement says | What you'll find right now |
|---|---|
| Project is complete | State's own page says complete; sign bridge work and expansion joint repairs are still generating closures |
| New lid connects the neighborhood to the Arboretum | Ped bridge ends at a crosswalk on Roanoke, not inside the Arboretum |
| Green space restored | Three-acre lid is open; East Montlake Park remains closed with no funded reopening plan |
| Transit access improved | Four Metro stops reopened on the lid after a six-year gap |
Buses Are Back, After Six Years
This part is an unambiguous win, and it's worth stating plainly. Buses hadn't served the SR 520/Montlake Boulevard interchange directly since 2019. King County Metro restored four stops on the lid in April 2025, covering routes that carry roughly 13,500 riders a day between the University District and the Eastside. County Executive Shannon Braddock called it "a big step forward for regional transit" when the stops opened, and for anyone commuting through this corridor, six years is a long time to route around a gap that's finally closed.
The Sign Fight Nobody Expected to Still Be Running
If you want the clearest evidence that "complete" is doing a lot of work in that sentence, look at what's happening on Montlake Boulevard this month. About three years ago, the rebuilt interchange came with large overhead sign bridges that a lot of neighbors didn't like. WSDOT communications manager Steve Peer told KIRO7 that residents said the structures were "really big for our neighborhood," and the pushback was strong enough that the agency halted a planned third sign bridge before it went up, ran a community survey, and formed a working group to find an alternative.
The fix WSDOT landed on is smaller mast-arm structures, the kind typically used for traffic signals, replacing the oversized overhead signs entirely. That swap requires two full weekend closures of Montlake Boulevard, a corridor WSDOT says can carry upwards of 100,000 vehicles in a weekend and ranks as the second-busiest intersection in Seattle behind Mercer Street. The first closure ran July 17 through July 20. A second, to finish removing the old structures and hang the new signs, is expected before the end of August. A separate, unrelated overnight closure hit eastbound SR 520 between I-5 and Montlake Boulevard on August 8 and 9 to repair a bridge expansion joint, a reminder that this stretch of highway is still an active work zone well over a year after the state marked the larger project done.
This Isn't Montlake's First Rewrite
None of this is out of character for the neighborhood. The Montlake Community Club has a track record of getting state agencies to revisit projects that were supposedly settled. In the 1960s, the club was part of the coalition that helped defeat the R.H. Thomson Expressway, a planned second north-south freeway that would have cut through the western edge of the Arboretum. The sign bridge campaign reads less like an aberration and more like the current chapter of a pattern this neighborhood has run before: state agency finishes something, residents decide it wasn't actually finished right, and the redesign happens anyway.
If You Live Here This Month
A few practical notes for anyone navigating the neighborhood while this settles out:
- Check sr520construction.com before planning a weekend drive through Montlake Boulevard. Closures are announced with only a few weeks' notice and WSDOT is recommending I-5 or Boyer Avenue as alternates during the mast-arm work.
- If your usual route to the Bill Dawson Trail was from the west side of Montlake Boulevard, plan on the new tunnel crossing instead. It adds a short detour but it's the only way through now.
- The Montlake Bridge still closes twice most Mays for neighborhood traditions that have nothing to do with the highway project: Opening Day of Boating Season and the Beat the Bridge charity run both shut it down to vehicle traffic for a few hours each.
- The Montlake Community Club brought back its Architecture Walking Tour again this year, with registration opening in June, and the club's Garden Tour tradition checks in at Cafe Lago on 24th Ave E, with nine gardens and three art studios along the route. Both are good ways to see the neighborhood's older housing stock up close while the highway story keeps unfolding a few blocks north.
The honest read on Montlake right now is that the state finished the parts it could point to in a press release and left the harder, less photogenic pieces, the park reopening, the direct trail link, the sign redesign, for later. If you live here, that's not a complaint so much as a fact worth knowing before you plan a commute, a dog walk, or a weekend around any of it.
For residents weighing what all this means for a home's long-term value in this stretch of Seattle, or for anyone thinking about where Montlake fits against nearby neighborhoods once the construction fully clears, Brad Hinckley tracks these changes as they happen, not after the fact.
