On Monday, Aug. 12, a southbound detour will be in place from 10 p.m. until 6 a.m. the following morning. Southbound I-81 traffic will be detoured at exit 132 (Dixie Caverns) onto Route 11/460 and back onto I-81 at exit 118 (Christiansburg). Signs and message boards will be in place to alert drivers.

As a safety precaution, slow roll lane closures during blasting will be in place on north and southbound I-81 beginning atapproximately 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.

• 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 beannounced as they are scheduled but are subject to change due to weather and work schedule.
