SR 115 begins just northeast of the
Chestatee River at an
intersection with
US 19/
SR 60 (South Chestatee Street), south of
Dahlonega, in Lumpkin County. This intersection marks the northern terminus of
SR 400. South of this intersection, US 19/SR 400 make up the Hospitality Highway, a
freeway that provides access to
Atlanta. It heads northeast to an intersection with
SR 52, east of the town. The two routes run
concurrent to the southeast for a little over . In a curving fashion, SR 115 heads northeast into White County and intersects with the western terminus of
SR 284 (Shoal Creek Church Road). Then, it enters
Cleveland, where it meets
US 129/
SR 11 (Main Street). On the eastern edge of the town is
Truett-McConnell College. Just east of the town is an intersection with the western terminus of
SR 255. To the southeast is
SR 384 (Duncan Bridge Road). Immediately after is an intersection with the eastern terminus of
SR 254. About later, the route passes over the
Chattahoochee River into Habersham County. To the northeast is an intersection with
SR 105 (Cannon Bridge Road). Just before entering
Clarkesville, Georgia is an intersection with the southern terminus of the
SR 17 Connector and the beginning of a concurrency with
SR 17 (Unicoi Turnpike). The two highways travel to the southeast until entering the town. Almost immediately, there is a crossing over the
Soque River. They curve to the northeast until they intersect
SR 197/
SR 385 (Washington Street, which is part of the old route of
US 441). At this intersection, SR 115 ends, and SR 17 heads south concurrent with SR 197/SR 385. The highway is mostly rural, except for the segments in Cleveland and Clarkesville. ==Major intersections==
