Slope Stabilization Project

detourFrom August through November, crews working for the Washington State Department of Transportation will stabilize a bluff in Purdy Canyon five miles north of Shelton in Mason County. The work will occur from the top of the 80-foot-high bluff adjacent to US 101. For the safety of the traveling public, lane closures and total highway closures will be prevalent throughout the project.

Starting around mid-August, US 101 will be reduced to a single lane of traffic around the clock between East Eagle Point Drive (milepost 340) and Skokomish Valley Road (milepost 339). A temporary traffic signal will provide traffic control. The signal will be designed to respond to real-traffic conditions to reduce delays to motorists.

In addition, between 7 p.m. and 6 a.m. each night over a nine-week period (exact dates to be determined), all lanes of US 101 will be closed at these same locations. Motorists traveling through the area will be directed around the closure on a detour that includes Brockdale Road, McReavy Road, Dalby Road and State Route 106. The detour adds 10.5 miles and about 20 minutes to motorists’ trips. Local traffic will be allowed as far as the actual construction zone.

The purpose of this project is to reduce the potential of slide-related closures of US 101. It also will increase motorists’ protection from hazards caused by falling debris.
