180th St SE - Phase II


Snohomish County's six-year Transportation Improvement Plan (TIP) identifies 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 23rd Ave SE and 35th Ave SE, along with bike lanes and sidewalks on both sides of the road, as a part of Phase II of this road improvement.


Phase II is at the 60 percent design phase. Right-of-way acquisition and SEPA review are scheduled to begin in 2019. Phase II construction has not yet been scheduled.
