This section provides information on MDOT’s funding estimates and projections for the multimodal Highway Program, as well as the Public Transportation and Aeronautics programs.
The 5YTP presents MDOT’s planned investments in all modes across the trunkline system over the five-year period spanning from 2027-2031 of approximately $19.4 billion. A total of $13.7 billion will be invested in the Highway Program with a continued focus on preservation, repair, and maintaining operations. Over these five years, an estimated $906 million will be invested in the Aeronautics Program and $8 billion in the Public Transportation Program, including bus, rail, marine, and public transit programs.
The Economic Benefit Analysis (EBA) of the Highway and Public Transportation Programs includes the benefits contributed by the capital and operation investment and benefits of travel efficiencies derived by project implementations. The travel efficiencies were assessed using the Transportation Economic Development Impact System (TREDIS) and the TREDIS Transit System Value Tool for the Passenger Transit program. TREDIS is specifically designed for transportation-related economic analysis and considers the broad economic landscape and factors critical to transportation projects. Its assessments, in this case, are based on employment projections from the U.S. Bureau of Labor Statistics and economic outlook data for the United States and Michigan sourced from the Research Seminar in Quantitative Economics at the University of Michigan.
