Slide cuts SR 4 on KM Mountain
Highway closed an undetermined amount of time
January 23, 2020
SR 4 will be closed for an undetermined time because of a landslide blocking the highway near the eastern base of KM Mountain.
The slide occurred late Thursday afternoon, dumping debris over a stretch of pavement at approximately milepost 25.
Because of the amount of material on the highway, SR 4 will remain closed until Washington State Department of Transportation Geo-Technical engineers can examine the hillside and determine what work needs to be done to reopen the highway.
Geo-techs came to the site Friday to start inspections. They pulled a WSDOT crew cutting trees off the slide when the material started to move.
The closure blocks the SR 4 route between Skamokawa and Grays River. Motorists traveling that route will have to find an alternate route.
According to the Wahkiakum County Department of Emergency Management Facebook page, the ferry Oscar B. is operating continuously to link Puget Island with Westport in Oregon.
