The U.S. Maritime Administration has opened applications for $488.6 million in Port Infrastructure Development Program (PIDP) grants. The funding will support infrastructure upgrades at ports and related intermodal connections across the United States.
The program will fund projects that improve port efficiency, safety, and reliability. Eligible investments include upgrades to port terminals, as well as supporting rail and highway connections that strengthen freight movement. Projects that enhance resilience, reduce emissions, and support seafood-related industries will also qualify.
At least 25% of the funding will support smaller projects at smaller ports. USDOT oversees the program through MARAD. The current funding round updates earlier guidance by increasing available funding and revising selection criteria.
Applications are due by June 26, 2026.
