ROUTE 688 (COTTON HILL ROAD) IMPROVEMENTS – Work is underway to reconstruct Route 688 (Cotton Hill Road) and improve drainage from Route 221 to west of Route 934 (Shingle Ridge Road) in Roanoke County. Flaggers may control traffic at times during mobilization and clearing operations. Motorists should use caution in the work zone and watch for signs.
