    West Lake Sammamish Detour Map

    Construction began in late April and is expected to be completed by winter 2021. Southbound traffic will be detoured at NE 24th Street to 173rd Ave SE. Northbound traffic will be detoured along West Lake Sammamish Parkway. Local access will be maintained throughout construction. Area residents received a construction alert detailing the work and detours. 


    Transportation improvements will include new pavement, an 8-10-foot wide multipurpose path on the west side, a landscaped buffer, two 10-foot wide travel lanes and a four-foot shoulder on the east side. In addition to Utilities' work to replace water mains, other improvements will feature new lighting, landscaping, irrigation and storm drainage.
