GRANITEVILLE, S.C. (WRDW/WAGT) - One lane of Interstate 20 was closed Friday while crews did some work at the site of the now-demolished Old Vaucluse Road overpass. The interstate was down to one lane Friday between mile markers 12 and 13, according to the South Carolina Department of Transportation. The rebuilding of the overpass is on the fast track after a fiery crash brought it down nearly a week ago. Still, it will take months to rebuild. Gov.
