Virginia Department of Transportation is will be weeks before the section will be stable enough to reopen. Lou Hatter, spokesperson for VDOT Culpeper region, said the slide started May 3 and the 1.75 mile long portion of U.S. 250 between Va. 151 and Va. 6 was shutdown mid-day. Hatter said there's no definitive source of what caused the slide, but there are a few contributing factors. "That area is prone to ground movement because of the nature of the material that's there," he said.
