Georgia • United States of America
The Georgia Department of Transportation (GDOT) manages over 18,000 miles of state routes including critical freight corridors I-75, I-85, I-20, I-16, and I-95 converging on the Atlanta metro — the nation's third busiest freight hub. GDOT facilitates billions of dollars of goods movement annually, particularly through the Port of Savannah, one of the fastest-growing container ports in North America. The department administers commercial vehicle permits, truck route designations, and operates weigh stations across the state. Its NaviGAtor traffic management system and 511GA service provide real-time road information vital to freight carriers.

Notable Rules
Georgia is a critical southeastern freight corridor anchored by the Port of Savannah, one of the busiest container ports on the East Coast. Georgia allows a slightly higher single-axle limit (20,340 lbs) on state roads under its bridge formula. The Atlanta metro I-285 perimeter and the I-85/I-75 downtown connector generate extreme congestion — route accordingly.
