King County Road Services will grind and repave a 3.4-mile section of Southeast May Valley Road beginning Wednesday, Sept. 4.

The work will close lanes between state Route 900 and 229th Drive Southeast and will last approximately three weeks, starting with grinding and paving. Flaggers will direct traffic through the work zone when lanes are closed and local access will be maintained.

Message boards will be posted to warn motorists of delays. Please use an alternate route if possible, or expect delays up to 15 minutes when driving through the work zone.

This work is dependent on good weather and we will post project updates on King County’s Road Services website and their blog.
