Work began Wednesday to clear debris and remove a disabled commercial truck that was involved in a landslide late Tuesday along U.S. 30 about 20 miles east of Astoria.
The Oregon Department of Transportation said there is no estimate on when the road will reopen to travel. Work will continue Thursday and Friday. ODOT said in a recent release that there is no estimated time for reopening a single lane for travel with flaggers, but it will be no sooner than Friday, Dec. 2.
Work will continue Friday and through the weekend if necessary to reopen the highway as soon as it is safe to do so. The roadway will need to be assessed for damage and the hillside will need to be evaluated to determine if it is stable before the road can reopen.
David House, ODOT Region 2 communications director, said the driver of the vehicle pictured was not injured, and there were no other reported injuries or damaged vehicles due to the slide.
The landslide happened about 10:30 p.m. Tuesday at milepost 74 east of Astoria. It has closed the road in both directions. ODOT estimates the slide is about 110 feet wide and sent at least 1,800 cubic yards of mostly rock onto the highway. A geologist also found two car-sized sections of hillside that will need to be removed as they are large enough to block the highway again if they fell.
Crews will work through winter-like conditions, including Thursday’s snowfall to:
- Clear debris on the travel lanes
- Clear space along the hillside to catch any additional rocks and mud
- Repair any damage to the road surface, guard rail and signs
- Possibly set up a temporary barrier to catch falling material
- Possibly set up temporary travel lanes providing safe distance from the slide for travelers
Drivers traveling between the Portland area and the northern Oregon coast through the rest of the week should choose alternate routes, including U.S. 26, or OR 47 and 202. OR 47 has vehicle length restrictions and is not meant for commercial vehicles.
ODOT warns travelers not to rely on GPS system for information on detours on less developed roads. This is especially important during winter weather as much of the area is in higher elevations and not maintained for winter driving.
