The Montlake Lid, One Year In: How The Neighborhood Actually Uses It Now

For six decades, the shortest walk between East Montlake Park and the Arboretum required either a detour to the drawbridge or a nervy jog along a highway shoulder. The lid changed the geometry. What used to be the thing that split Montlake in two is now the connective tissue running through the middle of it, and a summer of watching neighbors use it has made the pattern clear.

If you already live here, the interesting question is not whether the project finished. It is which of the new routes have quietly become the daily ones, which buses actually stop where the signs say they will, and what the state is about to hand off to the city on the old Montlake Market corner.

The Loop That Didn't Exist A Year Ago

The three-acre lid, the 73-foot-wide land bridge east of it, and the shared-use tunnel under Montlake Boulevard were built as separate pieces of the same project. Used together, they make a walking loop of roughly a mile that a resident could not have strung together before construction. Here is the sequence most Montlake walkers seem to have settled on:

1. Start at the Lynn Street entrance to the Arboretum, cross Lake Washington Boulevard, and pick up the ramp onto the land bridge. The paved path is 14 feet wide, buffered on both sides by five-foot berms planted with native grasses, lupines, asters, and more, roughly 15,000 plants in all, which do real work muting the freeway hum below.
2. Cross the bridge to East Montlake Park. The viewing platforms at each end look out over Union Bay and the Arboretum wetlands rather than the interchange.
3. Drop south into the shared-use tunnel that runs under Montlake Boulevard. It links directly to the Bill Dawson Trail, which returns you toward Montlake Playfield without ever putting you on Montlake Boulevard's sidewalk.
4. From the playfield, walk east on the neighborhood greenway back to 24th Avenue East. You are now on the lid itself, on grass and paths where a highway overpass used to be.
5. Return to the Arboretum via the Lynn Street entrance you started at.

None of the five segments is dramatic on its own. Strung together, they replace what used to be a choice between the drawbridge detour and Montlake Boulevard's traffic.

Which Buses Actually Stop On The Lid

The transit hub on the lid is the piece most likely to catch residents off guard, because the answer is not "all of them." Direct-access ramps in the SR 520 median feed a set of stops on the lid itself, and the routing decisions were made at the signal level, so it is worth knowing which buses reach the platform and which still leave you a walk.

The 545 case is the one that surprises people. Buses like the 545 headed to Downtown Seattle should be able to briefly exit the highway and stop in Montlake, but the signal configuration, controlled by the Seattle Department of Transportation, isn't being set up to allow that. If you are trying to get downtown from the lid, plan on transferring at UW rather than waiting for the 545 to appear at your feet.

For context on how long this gap has run, buses haven't directly served the 520/Montlake Boulevard interchange since 2019, when the "Montlake Flyer" stop that buses used to let passengers off right along the highway closed. Six years without a direct stop is why the return of the 255 and 542 to the lid feels bigger than a schedule change.

The Tunnel Almost Nobody Talks About

The shared-use tunnel under Montlake Boulevard is the least photographed piece of the project and probably the most useful for anyone who bikes to work. It carries the Bill Dawson Trail under the boulevard with separated walking and biking channels, so cyclists coming off the 520 Trail no longer have to negotiate the Montlake ramps on the surface.

There is a catch worth knowing. Bill Dawson Trail users who are used to connecting to Montlake Boulevard from the west, near the NOAA Fisheries building, may be disappointed to find that they can no longer make that connection, but will instead have to go through the tunnel and circle back. The old shortcut is gone. The new route is safer, longer by roughly a block, and only obvious once you have walked it once.

Why This Summer Feels Different

Construction did not so much end in Montlake as move west. The next phase, the Portage Bay Bridge and Roanoke Lid, is a seven-year, $1.5 billion 520 Portage Bay Bridge and Roanoke Lid construction project, and the noise, closures, and staging are now happening on the other side of the ship canal. For the first summer in roughly five years, the corner of Montlake north of the interchange is not a work zone.

The Arboretum Foundation has been direct about what the new bridge changes for access on foot and by bike:

"This is an exciting milestone. Improving accessibility to the Arboretum's plant collections, natural areas, and programs is a major priority for us, and the new bridge, and Montlake Lid transit hub, will help us better connect to the City and bring more people face to face with the wonders of nature."

That comes from the Foundation's Interim Director Elizabeth Lunney, and it points to a shift in how the Arboretum reads itself: not as a place you drive to and park at, but as one you walk into from the north side of the freeway.

Programming has followed. The Seattle Chamber Music Society's Concert Truck brings free classical performances into the Arboretum each summer, and the Foundation runs a free community yoga series with rotating local instructors. Neither one requires driving in through Madison Valley if you are coming from Montlake proper. The land bridge is now the shortest route from most of the neighborhood.

For residents who want to see the pre-lid neighborhood while it is still legible, the Montlake Community Club's architecture walking tour has reopened registration this year. The route pre-dates the interchange rebuild by decades, and it reads differently now that the highway is a landscaped lid rather than a trench.

The One-Acre Question On East Montlake Place

The most consequential Montlake story of the summer is not the lid itself. It is the one-acre lot at 2625 East Montlake Place East, where the Montlake Market and a 76 gas station stood before WSDOT took the parcel for construction staging.

In June, the Seattle City Council's housing committee took up a bill that would authorize the Seattle Office of Housing to use $6 million in appropriation from the state legislature to acquire the surplus Washington State Department of Transportation property at 2625 East Montlake Place E for the development of 50 owner-occupied, permanently affordable homes.

Two details from the Office of Housing's proposal are worth reading closely for anyone who owns a home nearby. The department has described the Montlake area where the development would take place as an "amenity-rich neighborhood, without affordable homeownership," and referenced upzoning expected to eventually be part of Seattle's next phase of comprehensive plan updates. And the design brief itself encourages housing with "2+ bedrooms for families," plus designs with "trees/greenery between the homes and 520, as well as other green building and pollution mitigation strategies" including "ground-floor commercial if feasible."

Ground-floor commercial matters. The block lost a corner store and a gas station when the state bought the parcel, and Montlake has been walking uphill for a market ever since. Whether the redevelopment restores any of that will depend on which developer the city selects and how the RFP is written. It is the sort of neighborhood detail that will shape which corner people meet at on a Saturday morning three years from now.

A Few Practical Notes For The Rest Of The Summer

• The lid's grass panels are still settling in year one, and the Parks Department has been rotating irrigation and cordoning small sections. If you walk a dog on the lid, the posted signage changes month to month.
• The land bridge's viewing platforms face west into afternoon light. For photography, morning is quieter and the plantings read greener.
• Route 48 southbound riders should still plan on the Roanoke Street stop rather than the lid. The walk is roughly six minutes from the lid platform.
• The Portage Bay work west of Montlake is expected to generate periodic overnight closures on SR 520 through the rest of the decade. Sign up for WSDOT's weekly construction email if you commute west in the early morning.
• The Montlake branch library, in its 5,650-square-foot building on 24th Avenue East, sits directly on the new walking axis between the lid and Interlaken Park. It is one of the easier stops to fold into a loop.

The larger point is that a piece of infrastructure most residents endured for five years has quietly become the geometry that organizes the neighborhood's daily habits. The Arboretum feels closer. The bus stops that vanished in 2019 came back in a different form. And a one-acre parcel on East Montlake Place is about to decide what the corner looks like for the next generation.

If you are thinking about what all of this means for your own house, whether that is timing a sale, weighing a renovation against the changing streetscape, or reading the market with the Portage Bay project still ahead, that is the kind of local read Kyle Mumma and the Mumma Homes team are built for.
