As summer winds down, work continues to ramp up on the SR 520 Montlake Project – literally. In preparation for a significant traffic shift later this fall, crews are building a new, temporary off-ramp to Montlake Boulevard that travelers will use for much of the project.
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 temporarily open before the game. (See details below)
- The SR 520 Trail across Lake Washington will be open from the Evergreen Point Lid as an out-and-back option on the floating bridge portion of the trail.
- Bicycle and pedestrian access across the 24th Avenue East overpass will close Friday night, Sept. 13, and remain closed for the duration of the project. A detour route will be open along Montlake Boulevard.
What to expect on Saturday, Sept. 14 – Husky game day travelers and tailgaters

What to expect – bicyclists and pedestrians
- For SR 520 Trail users on the Eastside during the weekend closure, the trail will be open from the Evergreen Point Lid to approximately the western-most sentinel tower as an out-and-back option on the floating bridge portion of the trail, but 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 re-open over the new Montlake lid. During project construction, detour routes will be available along Montlake Boulevard.
- Monday morning, Sept. 16, a new connection will open from the SR 520 Trail to Montlake Boulevard just north of the Montlake Boulevard off-ramp.
