The highway bearing left is the Old Quaker road, on of Georgia´s earliest vehicular highways. It was opened about 1769 to provide a direct way from Savannah to a Quaker settlement centering around Wrightsboro in today´s upper McDuffie County.
The Quaker road was one of the longest and most important routes of colonial Georgia. Much of the original way remains in use.
