  • In Nov. 2013, crews reopened US 101 to two lanes through the Purdy Canyon north of Shelton.  
  • WSDOT would like to thank residents and commuters for their patience while this project was under way. 


The detour is no longer necessary, as crews reopened US 101 to two lanes of traffic on Nov. 2013.

Why is WSDOT stabilizing these slopes?
The slope was unstable and a chronic issue resulting in emergency maintenance and road closures. To stabilize the slope, WSDOT removed 76,000 cubic yards, or about 7,600 dump trucks, of dirt and material and reshaped the slope. 

The End Result
The slope stabilization reduces the potential for slide related closures of US 101 and increases the protection of motorists from rock fall hazards.

Project Benefits
Reduced slides and emergency closures are the primary benefits, but this work also reduces maintenance costs associated with cleaning up fallen rocks and repairing the roadway.
