Organization

The Department of Transportation 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 at least four 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 capitol city. TDOT has approximately 4,200 employees.

History

The predecessor to the Tennessee Department of Transportation was created by legislative act in 1915 when the first administrative agency for highways was created and the first highway commission to guide its activities. 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 in addition to highways.

Funding

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 and bonds.
