Another round of blasting will slow traffic on Interstate 77 in Carroll County Wednesday.
The Virginia Department of Transportation says the blasting should occur around 1:00 p.m. between mile markers 2 and 4. That's near the North Carolina state line.
Traffic in both directions will be slowed by a rolling roadblock starting around 12:30 p.m.
Crews are removing rock along a slope between mile markers 2 and 4.
