SE May Valley Road to close up to 10 weeks for Fifteen Mile Creek Bridge replacement

SE May Valley Road near Issaquah-Hobart Road will close completely starting June 15 for up to 10 weeks to replace the 1932-era Fifteen Mile Creek Bridge #493C. The full closure affects all vehicles, pedestrians, and bicycles, with a signed detour route in place. The new bridge will add safety features including 8-foot shoulders for walking and biking, modern railings, and increased span length to improve creek flow and reduce flooding risk.
