Project Description

The Bothell Crossroads project realigns State Route 522 to the south between Hall Rd and 102nd Ave NE. The highway will consist of two travel lanes in each direction, left turn lanes, and sidewalks separated from traffic by tree-lined medians. Connecting streets (NE 180th St, 98th Ave NE, and SR 527) will be extended to reach the new alignment and provide pedestrians additional opportunities to move between downtown and the Park at Bothell Landing.

The existing intersection of SR 522 and SR 527 performs poorly and is expected to degrade further without action. Today, over 44,000 vehicles pass though this intersection daily. This project will improve traffic congestion and increase safety on this critical commute and freight corridor both now and into the future.

The Bothell Crossroads project consists of three construction phases:

Phase I
Phase II
Phase III
