History
Prior to 1915, the state had no central authority governing construction and maintenance of roads. The governor, legislature, other road associations, and local governments all attempted to serve these tasks, leading to a lack of planning and management. In 1915, a State Highway Commission was created to organize transportation services. The original commission consisted of six volunteer members. As responsibilities of the commission grew, this became inadequate, and in 1919 the commission was replaced with three paid members. By 1922, roads in Tennessee were behind surrounding states.
Governor Austin Peay created a new Department of Highways and Public Works and appointed J.G. Creveling, Jr. as the single commissioner. Peavy also implemented a tax of two cents per gallon to fund the new department. The collapse of the banking system in 1930 resulted in significant losses for the state and led to an inability to fund the department. All of its workers had to be released. However, in 1933 the

system brought a massive boom to the department. In 1972, due to its expanding role in all modes of transportation, it was renamed the Tennessee Department of Transportation. In the 1980s, TDOT began the $3.3 billion Better Roads Program to clear a backlog of projects and improve aging roads. In 1989, the gas tax was set at 21.40 cents per gallon to help fund this project. Through the 1990s and early 2000s, the department began working on ways to improve efficiency and involve communities.

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. Tennessee operates on a "pay as you go" system by using available revenues resulting in no debt service. Tennessee is one of three states in the nation that does not finance transportation through bonding. Critics of this mechanism claim that it inhibits the ability of the department to sufficiently complete necessary infrastructure improvements.

The victim's family subsequently received a $3,000 bill from TDOT for damage caused to the guardrail. TDOT later apologized for the bill and called it a processing error. At least three other deaths within a 15-month period were also caused by this type of device.
