Route description
SR 18 travels east from its western terminus in West Point in Troup County, crosses I-85 just east of West Point, and dips slightly southeasterly into northern Harris County, where is crosses I-185 and continues to Pine Mountain on the county line with Meriwether County. Turning northeast, SR 18 travels to Greenville in central Meriwether County, and is concurrent with US 27/SR 1 from their intersection south of Greenville into downtown Greenville, where SR 18 turns southeast, is concurrent with SR 109, and travels to Woodbury.
Turning east and crossing into Pike County, the route again turns northeast and travels through Molena, where its concurrency with SR 109 ends, into Concord, where it curves east and travels to Zebulon. Curving once again to the southeast, SR 18 crosses into Lamar County and travels to and around Barnesville, where it begins a concurrency with US 41/SR 7, before heading into Forsyth in Monroe County, ending its concurrency with US 41, and where it crosses I-75 shortly after leaving Forsyth. The highway continues east into Jones County and enters Gray, where it is briefly concurrent with US 129, SR 11, and SR 22, and where it turns southeast once more in the direction of Gordon in Wilkinson County.
In Gordon, the highway turns south and southeast, crosses into Twiggs County, and reaches its eastern terminus in Jeffersonville.
The only segment of SR 18 that is part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility, is the concurrency with US 27/SR 1 in Pine Mountain.
