Fiscal Year 2026 United States Marine Highway Program (USMHP)

The U.S. Department of Transportation’s Maritime Administration is soliciting applications for Fiscal Year 2026 funding under the United States Marine Highway Program, authorized by 46 U.S.C. 55601, to support projects that offer coordinated, efficient alternatives to landside transportation and help alleviate congestion on roads and highways. Eligible projects must either provide or expand marine-based transportation services using vessels documented under 46 U.S.C. chapter 121, promote the use of Marine Highway Routes by shippers, and contribute to reducing dependency on land-based freight networks. The program prioritizes initiatives that enhance the capacity, coordination, and sustainability of waterborne freight systems while aligning with national goals for infrastructure resilience and environmental efficiency. Applications must be submitted by the deadline of August 31, 2026, and are open to eligible entities seeking grants to develop, improve, or promote Marine Highway projects. The solicitation is issued under number 693JF725R000010, and inquiries should be directed to Kelly B Mitchell-Carroll, the designated Grantor, via email at fred.jones@dot.gov or phone at 202-366-9714. Although no specific set-aside or NAICS code is provided, the funding opportunity is open to federal and non-federal applicants pursuing marine transportation innovations that meet the statutory requirements. All projects must demonstrate measurable outcomes in reducing landside congestion and increasing reliance on marine highways as a viable freight solution across the United States.
