The Tribal Transportation Program (TTP) is the largest program in the Office of Federal Lands Highway. Established in 23 U.S.C. 202 to address the transportation needs of Tribal governments throughout the United States, the program is receiving $465 million in FY 2016, with increases of $10 million per year to $505 million in FY 2020, as established in Public Law 114-94, Fixing America’s Surface Transportation Act (the FAST Act).
The purpose of the Tribal Transportation Program is to provide safe and adequate transportation and public road access to and within Indian reservations, Indian lands, and Alaska Native Village communities. A prime objective of the TTP is to contribute to the economic development, self-determination, and employment of Indians and Native Americans.
The Tribal Transportation Program is funded by contract authority from the Highway Trust Fund and is subject to the overall Federal-aid obligation limitation. Funds are allocated among Tribes using a statutory formula based on tribal population, road mileage and average tribal shares of the former Tribal Transportation Allocation Methodology (TTAM) formula.
