Tennessee • United States of America
The Tennessee Department of Transportation (TDOT) manages over 14,000 miles of state highways through a state known as the 'Volunteer State's Freight Crossroads.' Key corridors include I-40, I-24, I-65, I-81, I-75, and I-55, making Nashville and Memphis among the nation's top freight hubs. Memphis is the nation's second largest freight hub and home to FedEx World Hub. TDOT administers commercial vehicle permits, manages bridge weight restrictions, and operates the SmartWay Traffic Management System. The department provides Tennessee 511 for statewide road conditions and incident alerts, and coordinates with adjacent states on major freight corridor improvements.
