(Astoria, OR) -- Highway 30 might remain closed until the weekend as crews work to remove a landslide about 20 miles east of Astoria. ODOT says their goal is to get at least one lane open with flaggers directing traffic. That might happen over the weekend. Crews need to remove the debris, stabilize the hillside and make repairs to the road. Highway 26 is the best alternate for drivers. ODOT cautions against using GPS mapping systems that could lead drivers onto roads that are blocked by snow.
