Multimodal Project Discretionary Grant Program (MPDG)

The Multimodal Project Discretionary Grant Program (MPDG) is the U.S. Department of Transportation's single application route for three large capital programs: Mega, INFRA, and Rural. It sits under DOT's Office of the Secretary and funds public infrastructure projects with regional or national significance, from freight corridors to major bridge and port work. The program supports states, metropolitan planning organizations, local governments, tribal governments, transit agencies, multi-jurisdictional groupings, and port authorities. In the most recent Rural round, DOT received 142 applications requesting $7.75 billion and awarded $785 million across 24 projects, with Rural authorized at roughly $2 billion through 2026. The combined notice continues in FY26 and tracks current rural, freight, and safety priorities. The strongest submissions are public projects that can show a concrete multimodal benefit, a credible regional delivery plan, and enough scale to justify a discretionary federal award. The single-application structure matters most when one capital package has to align multiple jurisdictions or transport modes.

Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.
