SALEM – A project is currently underway on Interstate 77 in Carroll County to remove rocks along a slope between mile markers 2 and 4. There are several types of traffic impacts scheduled this summer to successfully remove rocks in this location.

Lane Closure
A lane closure on northbound I-77 reducing this three lane section of I-77 to two lanes is currently in place. A concrete barrier wall has been installed.

Rolling Road Blocks
Periodically, blasting or air bags may be used to remove rocks during this project. Blasting will require rolling road blocks in both directions of I-77 and air bag use will only require rolling road blocks for northbound traffic. The air bags are inserted into crevices in the rocks and inflated to loosen and push rocks out.

During a rolling road block State Police will slow traffic to clear the work zone area. The times and dates of the rolling road blocks and blasts are tentative and could be adjusted due to weather or work schedule. Drivers should expect delays in this area. Mobile message boards are in place to alert drivers.

On Thursday, June 22, rolling road blocks will be in place in the northbound and southbound lanes of Interstate 77 between mile markers 2 and 4 so crews can conduct two blasts in this area. The first rolling road block will begin at 8:30 a.m. The second rolling road block will be put in place after traffic from the earlier blast has cleared. Crews approximate the second blast may occur at10:30 a.m.

Air Bag Inflation
Two rolling road blocks will take place in the northbound lanes on Tuesdays, Wednesdays and Thursdays at 8:30 a.m. and 10 a.m. until late June.

Work on this project is scheduled to be completed by September 2012.
