The newly-erected traffic signal at Highway 21 and Old Augusta Road, just inside the Effingham-Chatham county line, is in flashing mode for now.
The state Department of Transportation will have message boards in place to advise drivers of the new signal, and if weather permits, the signal will go into full effect Tuesday.
“Unless something changes,” interim county administrator Toss Allen said, “it will be a working signal (Tuesday).”
That means drivers on Highway 21 should be aware that the 55 mph traffic could come to a halt at the intersection with Old Augusta Road. It also gives drivers on Old Augusta Road looking to turn left onto 21 a safe means to do so.
