The Tennessee Department of Transportation maintains and develops the highways in the state of Tennessee. Currently the state boasts 14,150 miles (22,772.2 km) of roadway, including 1,073 miles (1,726.8 km) of Interstate Highways and 13,077 miles (21,045.4 km) of State Highways.[1] All of the U.S. Routes in Tennessee have a state highway concurrent, though the state highway is hidden and only signed along the green mile marker signs that display mileage within each county. Since 1982, State Highways have been divided into primary and secondary routes. Primary State Highways are part of the Federal-aid primary highway system , whereas secondary highways are not.[2] For the complete list of State Highways see List of state routes in Tennessee.
