Another round of blasting is scheduled for Wednesday morning on Interstate 81 in Montgomery County, meaning potential delays for drivers.

The blasting is needed to fix an unstable slope near mile marker 124 in Montgomery County. This is all part of a truck climbing lane project being built by the Virginia Department of Transportation.

Weather permitting, the blasting is scheduled to start around 10:30 a.m. The Virginia Department of Transportation will put slow roll lane closures in place on I-81 North and South starting around 10:30 a.m.

I-81 South Traffic will be slowed starting at mile marker 128 (Ironto Exit(. I-81 North traffic will be slowed starting at mile marker 114 (Christiansburg Exit).

Here is the news release from VDOT:

SALEM – In order to reconstruct an unstable slope on southbound Interstate 81 near mile marker 124 in Montgomery County, periodic blasting will take place over the next several weeks. Weather permitting, a blast is scheduled for Wednesday, Aug. 7.

As a safety precaution, slow roll lane closures during blasting will be in place on north and southbound I-81 beginning at approximately 10:30 a.m. State Police will slow traffic in both directions to keep the area near the blast clear of traffic. Once the blast has occurred, traffic will be released to travel at a normal speed. Drivers should expect delays.

Signs and message boards will be in place to alert drivers of the following traffic impacts during blasting:

• Traffic will be slowed on southbound I-81 beginning at mile marker 128 and northbound I-81, starting at mile marker 114 at approximately 10:30 a.m. During blasting, the on-ramps will be restricted onto northbound Interstate 81 at exit 118 (Christiansburg) and onto southbound I-81 at exit 128 (Ironto).

• Flaggers will control traffic on Route 636 (Seneca Hollow Road and Friendship Road) during blasting.
Future blasting dates will be scheduled on weekdays at approximately 10:30 a.m. as needed. Blasting dates will be announced as they are scheduled but are subject to change due to weather and work schedule.

Additionally, a nighttime lane closure is scheduled for southbound I-81 on Wednesday, Aug. 7, from 9 p.m. until 6 a.m. the following morning.

Work on the truck climbing lane project is expected to be completed in November 2013. For traffic information and updates, visit
