Federal Aid Highway Programs (LPA)

Highway User Revenue Fund (HURF)

The Highway User Revenue Fund (HURF) Exchange was created by the Arizona Legislature in 1997 and is run at ADOT’s discretion to benefit rural cities, town, and counties. The program allows planning organizations and their local agencies to swap out federal funds for state highway funds to design and construct projects. The program was active from 1998 to 2009 and launched again in 2017. The program offers less restrictive design and construction standards, fewer requirements, less project oversight, and lower project costs.

Off-System Bridge

On December 4, 2015, the President signed the FAST Act into law (Pub. L. 114-94). The FAST Act amended the Surface Transportation Program (STP) contained in 23 U.S.C. 133, and changed the name to the Surface Transportation Block Grant Program (STBGP). As part of the STBGP, a special set-aside was designated for the funding of the Off-System Bridge Program.

The FAST Act continues (without change) the MAP-21 set-aside of a share of each State's STBGP apportionment for use on bridges not on the Federal-aid highway system ("Off-System Bridges"). The amount is to be not less than 15% of the State's FY 2009 Highway Bridge Program apportionment.

The purpose of the Off-System Bridge Program is to fund the Design and/or Construction for replacement or rehabilitation of the roadway bridges over waterways, other topographical barriers, other roadways, railroads, canals, ferry landings, etc. on bridges that are not on the Federal-aid highway system (local roads or rural minor collectors) when those bridges have been determined deficient because of structural deficiencies, physical deterioration, or functional obsolescence.
