Highways, Roads and Bridges - As enacted, requires TACIR to study sustainable funding sources that meet this state's future transportation infrastructure needs and submit its recommendations. - Amends TCA Title 4; Title 9; Title 54 and Title 55.

HB 736 requires Tennessee's TACIR (Tennessee Advisory Commission on Intergovernmental Relations) to study sustainable transportation funding options to address declining gas tax revenue from fuel-efficient vehicles and rising infrastructure costs. The study must assess current road and bridge needs, identify long-term revenue measures, explore alternatives to fuel-based taxes, and analyze funding models used by other states. TACIR must submit its recommendations to lawmakers by January 15, 2026, using existing resources without new funding. This bill directly affects TACIR and state agencies providing data, with potential future impact on how Tennessee funds road and bridge maintenance.
