The West Lake Sammamish Parkway SE, Phase 2, project is the second of five anticipated segments of the Parkway slated for improvements (from Interstate 90 to the Redmond border, south of NE 24th Street). Phase 2 work will extend from the Northeast 200 block to the Northeast 800 block (project map). The project will be done in coordination with Bellevue Utilities' West Lake Sammamish Parkway Water Pressure Project.
Construction began in April 2020 and is expected to be completed by winter 2021. The multipurpose path on the west side of the Parkway, north of Northup Way, opened for use in June 2021. A second phase of construction begins at Southeast First Street and ends in the 1900 block.
To complete this second phase of work a new detour route south of Northup Way is being implemented in mid-July 2021 (see map). The previous detour route ended. Area residents received a construction alert detailing the work and detours.
Transportation improvements 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.
