A sinkhole that’s 30 feet deep has closed part of WV 20 north of Hinton. The West Virginia Division of Highways said it is devoting everything possible to get the hole repaired quickly. West Virginia 20 is a vital route in and out of the area. Officials believe a failing drainage structure is causing the soil in the area to collapse on the shoulder of the roadway. Barricades have been erected to keep people from getting too close to the sinkhole while engineers determine the best solution to repair the damage.
