US 12 - Rimrock Lake Vicinity - Slope Stabilization - Complete October 2017

Project news

  • This project was completed in the fall of 2017.

Needs & benefits

Why did WSDOT stabilize the slopes above Rimrock Lake?
In the fall of 2017, crews closed a section of US 12 west of the Rimrock tunnel to remove loose rock above the hillside. 

Project Benefits
Safety: Crews reduced the potential for future slides.

Mobility: This project reduces the possibility of emergency closures and traffic delays due to rock slides.


  • September 2017: Project begins
