U.S. Route 220 and Virginia Route 666 in Alleghany County were re-opened to traffic Friday morning.

A 16-mile stretch of U.S. Route 220 had been closed to through traffic between Covington and Hot Springs since Feb. 24.

The road was closed when a slope failure occurred just north of its intersection with Dunbrack Road.

Virginia Department of Transportation crews expedited the work on Route 220 by  installing soil nails to stabilize the slope, then they rebuilt the roadbed and roadway. Contractors excavated the area affected by the slope failure, which was  about 150 feet in length.

VDOT?said traditional repair methods would have taken several months.

Contractors also worked to clear Virginia Route 666 in the Falling Spring area. That road also reopened  to traffic Friday morning, said Ken Slack, spokesman for the Virginia Department of Transportation’s Staunton District.

Contractors will now turn their attention to clearing Route 661 (Johnson Creek Road) in the Johnson Creek area, which was closed by slope failures Feb. 22.

“The contractor stopped working on Route 661 because we decided to focus first on Route 220 because of the higher concentration of traffic,” Slack said. “Now, we will go back to working on Route 661.”

Contractors are dealing with two slope failures on Route 661, he said.

Drivers in the Johnson Creek area are using a detour route. Route 661 is closed between Route 600 (Indian Draft Road) and Route 781 (Rucker Gap Road).

Slack said there is no estimate on when Route 661 will reopen. All work is weather permitting, he said.
