Transportation (Transportation Funding)

HB 4230 creates a new "neighborhood road fund" in Michigan's state treasury, funded by $100 million annually from income tax revenues (specifically from Section 695 of the 1967 Income Tax Act). This fund directly affects county road commissions, city and village road agencies, and the local bridge advisory board. Key provisions require $100 million yearly to be reserved exclusively for repairing closed, restricted, and critical bridges (managed by the advisory board), while the remaining funds are distributed to road agencies based on their road mileage - $100,000 per county commission plus a mileage-based share for all counties, and similarly for cities/villages. The bill specifies these funds must cover road preservation, maintenance, and preventative work without requiring local matching funds.

SB 695 allows regional transit authorities in Michigan to charge an extra $1.20 per $1,000 of a vehicle’s value (on top of standard registration fees) for transit funding, but only if approved by voters in a November election. It requires ballot measures to specify how funds will be used and limits spending to transit projects. The tax applies to regular vehicle registrations in transit regions, excluding company test vehicles (e.g., manufacturer-owned vehicles used for testing). It takes effect January 1, 2027, pending approval of related legislation. This change directly affects vehicle owners in participating transit regions through their registration costs.

SB 578 creates a new Neighborhood Roads Fund to support maintenance of local neighborhood streets and modifies the existing Movable Bridge Fund to improve bridge infrastructure funding. The bill changes how these funds are managed and allocated, directly affecting local governments responsible for road and bridge upkeep. Key provisions include establishing dedicated funding sources for neighborhood roads and adjusting eligibility rules for bridge repair projects. These changes clarify state funding streams for community infrastructure without altering tax rates or new construction policies.

HB 4951 creates a new tax on marijuana sales to fund state road infrastructure projects. It directly affects marijuana businesses (which pay the tax) and state transportation budgets (which receive the revenue). The key mechanism establishes a dedicated funding stream, redirecting tax revenue from cannabis sales toward repairing and maintaining roads, rather than general state funds. The bill became law immediately upon the Governor's approval on October 7, 2025.

HB 4183 increases the motor fuel tax rate and expands the types of fuels subject to the tax under Michigan law. It directly affects motor fuel sellers (like gas stations) and consumers through higher costs for gasoline and other taxed fuels. The bill amends Section 8 of the 2000 Motor Fuel Tax Act (MCL 207.1008) to implement these changes, which became law immediately upon approval by the Governor on October 7, 2025.
