MONTGOMERY COUNTY, Va. — The blasting schedule on Interstate 81 in Montgomery County will change after Labor Day.
The Virginia Department of Transportation says it will expand blasting days from Monday through Thursday to include Fridays. The first Friday blasting day is scheduled for September 9.
The traffic management during blasting operations will continue as follows:
- Blasting may be scheduled daily, Monday through Friday, between 11 a.m. and noon.
- Southbound I-81 traffic will be detoured off I-81 at exit 132 (Dixie Caverns) onto Route 11/460 and back onto I-81 at exit 118 (Christiansburg). The detour will be implemented daily sometime between 10:30 a.m. and 1 p.m. and will be removed immediately once slopes have been scaled and the road is deemed safe for the traveling public. State Police will assist with this detour. A right lane closure will be in place on southbound Route 11/460 during the detour.
- On northbound I-81, a rolling road block starting at mile marker 114 sometime between 10:30 a.m. and 1 p.m. will be used to slow traffic. During blasting, the on-ramps will be restricted onto northbound Interstate 81 at exit 118 (Christiansburg) and onto southbound I-81 at exit 128.
- Flaggers may control traffic on Route 636 (Seneca Hollow Road and Friendship Road) and on Route 642 (Den Hill Road) during blasting.
Blasting on the project is expected to continue through spring 2012. Work on the truck climbing lane project is expected to be completed in November 2013.
