Tribal HPP Program History

Prior to BIL

The Indian Reservation Roads High Priority Projects Program (IRRHPP) was created through negotiated rulemaking and documented at 25 CFR 170 (July 19, 2004).  Under these regulations, the IRRHPP was a set-aside from the Indian Reservation Roads Program (IRR) and was funded from 2005 through 2012.  Applications were ranked by a committee comprised of BIA, FHWA and tribal participants using the scoring matrix specified in the regulations.  In 2012, $28,533,502 was awarded to Tribes through the IRRHPP.  

The Tribal HPP Program was enacted and codified in 23 U.S.C. 202, through Public Law 112-141 (MAP-21 §1123 dated July 6, 2012) and a fact sheet was developed (  The Tribal HPP Program was modeled after the former IRRHPP in 25 CFR 170 (July 19, 2004) but MAP-21 changed the funding from a TTP set-aside to an authorized appropriation of $30 million per year from the General Fund.  Although MAP-21 authorized the program, there were no appropriations for the program under MAP-21 or the FAST Act.
