Tennessee Department of Transportation

From Wikipedia, the free encyclopedia

The Tennessee Department of Transportation (TDOT) monitors all road projects in the state of Tennessee. It is headquartered in Nashville, Tennessee, located at the confluence of three major Interstate Highways.

Major projects TDOT has recently been involved in include the construction of a ramp between Interstate 40 and Briley Parkway in west Nashville, widening of I-40 at the Interstate 24 junction in southeastern Nashville, the construction of State Route 840, the Outer Memphis Beltway I-269, and the extension of the Pellissippi Parkway I-140.

TDOT also manages the system of cameras and electronic signs around the state to deal with traffic hazards during peak volume hours. The Smartway cameras broadcast live to the major newsstations for morning news programs.
