The right lane of westbound State Route 18 will close from 8 a.m. to 2 p.m. Monday through Thursday for about three weeks starting Monday, Oct. 5, just east of Tiger Mountain summit.
Crews working for the Washington State Department of Transportation will perform sampling work along westbound SR 18 between mileposts 24 and 25 in support of the future SR 18, Issaquah Hobart Rd to Deep Creek Vicinity – Widening & Fiber project. One westbound lane will remain open each day during sampling work, which is planned through Oct. 22.
Travelers should expect delays and allow extra travel time during these daily lane reductions.
