Danville Public Works will be closing the intersection at Piedmont Drive and Old Mt. Cross Road Thursday.  Crews will be replacing damaged signal wires and during the repairs lights will be powered down.  Work will start around 7:30 and should be completed later in the afternoon.  There will be no left turns off of Piedmont drive during this time.  Individuals wishing to turn onto Piedmont from Old Mt. Cross will only be allowed to make right hand turns to join the flow of traffic.  The same goes for those leaving the Piedmont Mall Parking lot.
