West Valley Highway/Longacres Way Project

Project Status Update

On Monday, March 7, 2022, construction will begin on West Valley Highway between I-405/S 156th  Street and Strander Boulevard. The plan is to start working on the north end of the project and work south, including the work on Longacres Way to the east. There will be lane closures as needed to allow the contractor to work, including some survey work.

 

Project Overview

This project will widen West Valley Highway to the east to add a third northbound lane between Strander Boulevard and I-405 ramp/S 156th Street intersection. New sidewalks will be added where none currently exist and a new mid-block pedestrian signal will be installed adjacent to the Pedestrian Bridge. Longacres Way will be restriped to include a two-way cycle track on the south side of the road and street/pedestrian illumination will be added. A new pedestrian flashing beacon will be built at the Interurban Trail intersection with Longacres Way. The overall project will increase mobility and safety of vehicles, freight, pedestrians, and bicyclists and will improvement the non-motorized connection to the Sounder Station. The funding comes from grants from the Transportation Improvement Board and Sound Transit in additional to Traffic Impact Fees and general revenue. Construction will start late in the first quarter of 2022 and is expected to be fully completed before the end of the calendary year.
