Senate Bill 2972 and House Bill 2986 propose significant changes to the governance of Carroll County's roads and highways by repealing Chapter 148 of the Private Acts of 1986, as amended. The bill establishes the Office of Highway Supervisor, which will serve as the Chief Administrative Officer under the Tennessee County Uniform Highway Law. The Highway Supervisor will be elected by the voters of Carroll County during the general election in August 2026 and will serve a four-year term, with the first office term beginning on September 1 following the election. The bill ensures that the current Highway Supervisors' terms are not affected by this new legislation.

Additionally, the bill outlines the qualifications, duties, and responsibilities of the Highway Supervisor, which will align with the existing Tennessee County Uniform Highway Law. In the event of a vacancy, the County Legislative Body will appoint a replacement. The bill requires a two-thirds vote from the legislative body of Carroll County for it to take effect, with provisions for immediate implementation for the purpose of approval or rejection.
