The Tennessee Department of Transportation (TDOT) is a multimodal agency with statewide responsibilities in roadways, aviation, public transit, waterways, and railroads. The mission of TDOT is to provide a safe and reliable transportation system for people, goods, and services that supports economic prosperity in Tennessee.
The major duties and responsibilities of TDOT are:
TDOT is headed by a single commissioner who is appointed by the governor. The department is organized into four regions of the state: Knoxville (Region 1), Chattanooga (Region 2), Nashville (Region 3), and Jackson (Region 4). Each region is subdivided into three districts and those districts are further subdivided into county facilities. TDOT has at least one facility in all of Tennessee’s 95 counties. Several administrative offices, including the commissioner and staff, operate from the TDOT headquarters in downtown Nashville, the state’s capital city. TDOT has approximately 3,900 employees.
TDOT is organized into four regions, which are divided into districts and then further subdivided into county facilities. The table below indicates the region, the districts in each region, the counties in each region and district, and the locations of the district offices.
The predecessor to TDOT was created by legislative action in 1915 when the first administrative agency for highways and the first highway commission to guide the administrative agency's activities were created. The highway commission was directed by six non-compensated commissioners which included the governor, the state geologist, and the dean of the University of Tennessee Engineering School. In 1919, transportation was organized under a three-commissioner structure which remained in place until 1923. The agency was reorganized in 1923 with the establishment of a single commissioner in Chapter 7 of the Public Acts of 1923. Under the single commissioner structure in 1923, J.G. Creveling, Jr. was appointed by Governor Austin Peay. In 1972, the agency name was changed to the Tennessee Department of Transportation to reflect other modes of transportation in addition to highways.
Funding for the state transportation system in Tennessee comes from a fund that is separate from the state’s general fund which operates most of the other state agencies in Tennessee. Transportation revenues come from both federal transportation monies and from state funding resources. Those state funds come from a combination of dollars collected from gas and diesel tax revenues, titling and registration fees. Tennessee operates on a "pay as you go" system by using available revenues resulting in no debt service.
