2 Lanes Closed on I-81 Near Blacksburg

Posted: Updated:

The Virginia Department of Transportation has closed both southbound lanes of Interstate 81 near Blacksburg due to an unstable slope. Traffic is being detoured at exit 132 to Route 11 and back on the interstate in Christiansburg.

Crews have been blasting as part of a project to construct a truck climbing lane between mile markers 120 and 125. During a blast Monday, a 50-foot existing crack in a slope increased to approximately 120 feet in length.

Correcting the problem could take 10 days.
