Amends TCA Title 12; Title 54 and Title 55.

Tennessee HB2230 expands the authority of the Department of Transportation to set tolls on existing transportation facilities that are part of the state highway system or interstate and national defense highway system, specifically at state borders. The bill affects transportation infrastructure and users of these facilities by allowing tolls to be implemented when new vehicle travel lanes are added or when high occupancy vehicle (HOV) lanes are converted to high occupancy user fee lanes on or after July 1, 2026. Key provisions include the stipulation of toll implementation linked to specific infrastructure changes at border locations.
