(Siletz, OR) -- Oregon Highway 229 near Siletz remains covered by a massive landslide. The Oregon Department of Transportation doesn't know how long it'll take to reopen. Engineers need to determine how the slide will be removed and the road rebuilt. ODOT has created an "OR 229 Landslide" webpage. It updates progress on the project. There is a detour, but ODOT says drivers should expect longer travel times on alternate routes.
