The route crossing at this point is the Sunbury Road, one of the longest vehicular thoroughfares of post-Revolutionary Georgia. it was laid out in the early 1790´s from Greensboro via today´s Sparta and Swainsboro to the town of Sunbury, a port on the Midway River in Liberty County. The route was noted for its elevated course and small number of stream crossings. When Sunbury, once a leading Georgia port, lost commercial significance, the road declined in arterial importance. Much of the old way, however, continues in daily use.
