The Indian Reservation Roads Program (IRR) is part of the Bureau of Indian Affairs (BIA) and is meant to meet the transportation needs of American Indians in the United States, American Indian tribes, and Alaska Natives. These roads, also known as BIA Roads are given to tribes by providing funds for planning, designing, construction, and maintenance activities. The authorizing legislation is the highway authorization act (currently the Safe, Accountable, Flexible and Efficient Transportation Equity Act – A Legacy for Users (SAFETEA-LU)) and codified in Title 23 U.S.C. and 25 C.F.R. Part 170.
