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.
