Project Overview

This project will rehabilitate approximately 2,900 linear feet of West Lake Sammamish Parkway, from just north of Marymoor Park Road to Leary Way. Crews will grind down the old pavement and overlay new asphalt to extend the useful life of this roadway section. This project is partially funded by Federal highway dollars.

Travelers should expect:

  • Work from May through June of 2025.
  • Lane closure on West Lake Sammamish Parkway during the day from 9:30 a.m. to 3:00 p.m. 
  • Lane closures at night along Westlake Sammamish Parkway and the eastbound 520 off-ramp. 
  • The ramp will be fully closed for part of the construction, with traffic detoured to Redmond Way off-ramp.
