Port Infrastructure Development Program (PIDP)

General Grant Program Information

The Port Infrastructure Development Program (PIDP) provides funding for projects that improve the safety, efficiency, or reliability of the movement of goods into, out of, around, or within ports, including the improvement of facilities within, or outside of and directly related to operations of, or an intermodal connection to, coastal seaports, inland river ports, and Great Lakes ports.

Large projects (over $11.25M Federal request) in contiguous states require benefit-cost analyses (BCA) that demonstrate cost effectiveness. Small projects at small ports ($11.25M or less Federal request at ports with less than 8M tons of annual cargo), or projects in non-contiguous States and Territories, may not require a BCA as outlined in the Notice of Funding Opportunity. For more information about BCAs, see What Is a Benefit-Cost Analysis? and USDOT's Benefit-Cost Analysis Guidance for Discretionary Grants.

Eligible Uses

Eligible uses include capital projects that improve the safety, efficiency, or reliability of:

  • The loading and unloading of goods at the port, such as for marine terminal equipment;
  • The movement of goods into, out of, around, or within a port, such as for highway or rail infrastructure, intermodal facilities, freight intelligent transportation systems, and digital infrastructure systems;
  • Operational improvements, including projects to improve port resilience;
  • Environmental and emissions mitigation measures; or
  • Port and port-related infrastructure that supports seafood and seafood-related businesses, including the loading and unloading of commercially harvested fish and fish products, seafood processing, cold storage, and other related infrastructure.

Funding Information

The Infrastructure Investment and Jobs Act (IIJA) provided $2.25 billion for the PIDP program over 5 years (2022-2026), $450,000,000 of which was made available in fiscal year (FY) 2026. In addition to the FY 2026 IIJA PIDP funds, FY 2026 Appropriations Act funding, if appropriated, and unobligated prior year PIDP funds may be made available and awarded under this solicitation to eligible projects.

Federal cost-share for PIDP is 80 percent, but the Secretary of Transportation may raise the Federal contribution to higher than 80 percent for grant projects located in rural areas or small projects at small ports.
