HB 1589 mandates voter approval for the construction of new toll projects. It prohibits toll project entities from proceeding with construction unless a majority of voters in each county where the project will be located approve the project in an election specifically held for that purpose. The bill outlines requirements for election procedures, including the designation of polling places and the project location. These provisions apply only to toll projects for which contracts are entered into on or after the act’s effective date of September 1, 2025.
