The highway crosses at this point the former course of the Sunbury road, one of the longest vehicular thoroughfares of post-reolutionary Georgia. It was laid out in the early 1790´s from Greensboro via today´s Sparta and Swainsboro to Sunbury, a port on the Midway River in Libery County. The Jefferson and Johnson county line follows this early route. The old way lost arterial significance when Sunbury, once a leading port, declined in commercial importance. From northern Emanuel county southward, much of the way remains in daily use.
