Senate Bill 1558, also known as House Bill 1569, proposes the repeal of Chapter 202 of the Private Acts of 1984 and Chapter 211 of the Private Acts of 1992, along with any other conflicting acts related to Obion County. The bill stipulates that the Obion County Highway Commission will cease to exist as of March 2026, and the Obion County Legislative Body will not fill any vacancies on the Commission that occur after the effective date of the act. Additionally, the highway superintendent or their designee is required to report to the Legislative Body at regularly scheduled meetings.

The bill includes a provision that it will only take effect if approved by a two-thirds vote of the legislative body of Obion County within ninety days of its passage. The approval or disapproval will be certified by the presiding officer of the legislative body to the secretary of state. Furthermore, the act is declared to be severable, meaning that if any provision is found invalid, it will not affect the validity of the remaining provisions. The act will be effective upon becoming law for the purpose of approval or rejection, while for all other purposes, it will take effect as outlined in the approval process.
