SR 75 begins at an intersection with US 129/SR 11 (North Main Street) in Cleveland in White County. This intersection also marks the southern terminus of SR 75 Alternate, which runs concurrent with US 129/SR 11 to the northwest. SR 75 heads north-northeast, past White County Park, to an intersection with the northern terminus of SR 384. About 1.2 miles (1.9 km) later, the road crosses over the Chattahoochee River. Then, SR 17 (Unicoi Turnpike) begins a concurrency with it to the northwest. Immediately after is another crossing of the Chattahoochee River. In Helen, a Germany-themed town, they cross over the river again. They begin to parallel the river to the northwest. Just outside town, they meet the northern terminus of SR 75 Alternate and enter the Chattahoochee-Oconee National Forest. They head north and north-northeast on a curving fashion through the North Georgia mountains and cross into Towns County. They meet the eastern terminus of SR 180 and parallel the Hiawassee River for a while, before crossing over the river and heading to the north-northwest. They begin a concurrency with US 76/SR 2, just to the west of Macedonia. The four highways meet the eastern terminus of SR 288 and cross over a portion of Chatuge Lake. Then, they head northwest to the town of Hiawassee. In the northern part of town, SR 75 splits off to the northeast. It curves to the northwest, and circles back to the northwest, before leaving the Chattahoochee-Oconee National Forest, heads west, and curves to the north. It heads due north before a gradual curve to the north-northeast, just before meeting its northern terminus, the North Carolina state line. Here, the roadway continues as North Carolina Highway 175.
SR 75 is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.
This section needs expansion. You can help by adding to it. (May 2016)
The original southern terminus was at Georgia State Route 254 near the Mossy Creek and Skitt Mountain Golf Courses. This segment ran northwest into US 129/SR 11 and multiplexed with those routes until it reached Helen Way. Today, the segment between SR 254 and US 129 is named "Old Highway 75 South."
State Route 75 Alternate (SR 75 Alternate) is an 11.1-mile-long (17.9 km) alternate route that exists entirely within the central part of White County.
It begins at an intersection with US 129/SR 11 (North Main Street), where they meet the southern terminus of the SR 75 mainline (Helen Highway) in Cleveland. US 129/SR 11/SR 75 Alternate head northwest and leave town. A little ways outside of town, SR 75 Alternate splits off to the north-northeast. Little over 1 mile (1.6 km) later, the road enters the Chattahoochee-Oconee National Forest. It intersects the eastern terminus of SR 348 (Richard B. Russell Scenic Highway). The road continues to the north-northeast and meets its northern terminus, an intersection with SR 17/SR 75 (Unicoi Turnpike), just northwest of Helen.
