Highway Program funding

MDOT's FY 2024-2028 Highway Program is supported by a combination of state and federal funding sources. The total federal and state highway program funding expected for FY 2025-2029 is just under $11.9 billion, including $475 million in state bond financing as part of Governor Gretchen Whitmer’s Rebuilding Michigan Program. Federal revenue accounts for approximately 51 percent of this total and includes general fund appropriations from the Bipartisan Infrastructure Law, authorized in November 2022, approximately $200 million in discretionary grants awarded for specific projects, and an expected 2 percent annual federal revenue growth rate through FY 2026.

State revenues are supported by state fuel tax rates tied to an expected growth rate of 3.4 percent, state vehicle registration fees, and $234.6 million per year in an income tax redirect from the general fund, with an average of $48 million in excise tax on recreational marijuana appropriated annually.
