Be prepared for delays on both directions of travel on Interstate 81 on Monday.

Crews from the Virginia Department of Transportation will put slow-roll lane closures in place starting Monday morning because of blasting. Slow-roll lane closures for I-81 South start at Exit 132 (Dixie Caverns). I-81 North slow-roll lane closures start at Exit 114 (Christiansburg).

Also, VDOT will put lane closures in place from 10 p.m. to 6 a.m. on Monday night and Tuesday night on I-81 South.


Scheduled blasting on Interstate 81 in Montgomery County will cause southbound lanes to close from 10:00 p.m. to 6:00 a.m. the following morning from Sunday, August 18 through Tuesday, August 20.

Slow roll lane closures during blasting will be in place on north and southbound I-81 beginning at 10:30 a.m. Monday. Traffic will be slowed in both directions to keep the blast area clear of traffic. 

Drivers should expect slow moving traffic and delays.

If you're traveling south around 10:30 a.m. each day, traffic will be slowed starting at mile marker 128.

If you're traveling north on I-81, traffic will be slowed starting at mile marker 114 around 10:30 a.m. each day.

Flaggers will control traffic on Route 636 (Seneca Hollow Road and Friendship Road) during blasting, according to the Virginia Department of Transportation.

Blasting is subject to change based on weather conditions.

The blasting is part of the continuing construction on the five mile truck climbing project on southbound Interstate 81 in Montgomery County.
