US 101 - N of SR 107 - Stabilize Slope - Project map

US 101 Cosi Hill Vicinity Map

This section of US 101 in Grays Harbor County, also known as Cosi Hill, is the site of a large, slow-moving landslide under the highway. Despite ongoing maintenance efforts, further attention is needed to repair the slide-prone area. The goal of this project is to stabilize the slope adjacent to the road to reduce the risk of earth movement that could lead to unexpected roadway closures.
