In Lumpkin County, the intersection of Ga. 115 (Dahlonega Highway) and Ga. 52 at Copper Mines Road used to be a constant bottleneck. Vehicles would sit idling, then inching forward one car length at a time to await their turn at the 4-way stop. Things changed when the Georgia Department of Transportation (GDOT) redesigned the intersection into a roundabout, a.k.a. traffic circle.
