Port Infrastructure Development Program (PIDP) Grants

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) require benefit-cost analyses (BCA) that demonstrate cost effectiveness. Small projects at small ports, 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.

In addition to the FY 2025 IIJA PIDP funds, an additional $50 million in funding for the PIDP was made available through the Full-Year Continuing Appropriations and Extensions Act, 2025.

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.
