The Sunbury Road was one of the longest vehicular thoroughfares of post-Revolutionary Georgia. It was laid out in the early 1790s from Greensboro by way of present-day Sparta and Swainsboro to Sunbury, a port on the Midway River in Liberty County. The Jefferson and Johnson county line follows this early route. The road lost arterial significance when Sunbury, once a leading port, declined in commercial importance. From northern Emanuel County southward, much of the route remains in daily use.
