Snohomish County's six-year Transportation Improvement Plan (TIP) identifies several projects to improve conditions for pedestrians and motorists along the 180th St. SE corridor. One of these is a project along 180th St. SE beginning at the Bothell-Everett Highway (SR 527) intersection.

The county is proposing to add two lanes to bring 180th St. SE up to five-lanes between SR527 and 23rd Pl. SE (Phase I).

A second phase would extend the improvements between 23rd Ave SE and 35th Ave SE. Currently, the road consists of three lanes and there are gaps in the sidewalks. This project will also add sidewalks, bike lanes, curbs, and gutters.


Phase I is at 90 percent design and construction is tentatively scheduled to begin in 2019. Phase II is in the design report phase.
Phase II between 23rd Pl. SE and 35th Ave. SE is under consideration and has not yet been scheduled.
