Public comment period begins for ADOT’s Tentative Five-Year Construction Program

Proposed 2025-2029 focus: upgrading pavement conditions, improving major corridors
The Arizona Department of Transportation is seeking the public’s input on its latest program to improve and maintain the state’s highway system during the next five years, a proposal that includes several major widening projects while also improving pavement conditions.
The public can provide comments on the Tentative 2025-2029 Five-Year Transportation Facilities Construction Program in the following ways:
The public comment period for the FY 2025-2029 Tentative Five-Year Transportation Facilities Construction Program ends at 5 p.m. on May 24. 
A major emphasis of the proposed $7.9 billion tentative program is improving highway pavement and bridge infrastructure throughout greater Arizona, which encompasses areas outside of Maricopa and Pima counties. The plan would provide more than $2.4 billion for these high-priority improvements during the next five years. This amounts to an average investment of approximately $600 million per year to preserve, rehabilitate and replace pavement and bridges, including: 
  • $508 million in pavement projects on interstates 10, 17 and 40.

  • $690 million in pavement projects on other routes, including US 93 and 60, and state routes 64, 160, 260 and 347.

  • $170 million in bridge projects on the interstates and $82 million on other routes.

The program provides a total of $685 million over five years for projects that improve highway safety, efficiency and functionality, such as intersection improvements, smart technology and adding shoulders.The tentative program also allocates $495 million for projects that widen highways or improve interchanges across greater Arizona, including:
  • Constructing the Interstate 40/US 93 West Kingman Interchange.

  • Widening and improving US 93 between Wickenburg and I-40 in Kingman, including expanding three segments of the highway from two to four lanes. The US 93 improvements include the ongoing widening project near Wickenburg, along with new projects near Cane Springs and Big Jim Wash.

  • Widening the last two-lane section of State Route 260 in the Lion Springs area between Payson and Heber-Overgaard. This will complete a four-lane divided highway along the entire SR 260 corridor.

In the Maricopa County region, the program features $2.5 billion in construction projects planned in conjunction with the Maricopa Association of Governments. Those projects include:
In Pima County, in association with the Pima Association of Governments, the program includes $849 million toward:
  • I-10 improvements from Kino to Country Club, which includes building a new interchange at I-10 and Country Club Road, while also widening I-10 in the area starting in 2025.

  • Reconstructing the I-19 interchange at Valencia Road starting in 2025.

Funding for the statewide program comes from federal and state dollars, in addition to money generated by users of transportation services in Arizona, primarily through gasoline and diesel fuel taxes and the Arizona vehicle license tax. Both the Maricopa and Pima county regions have voter-approved sales taxes for transportation that funds expansion projects.ADOT’s five-year program is developed by working closely with local governments and regional transportation planning organizations to prioritize projects that are ready to build or design. The State Transportation Board is expected to consider formal action on the program at its June 21 meeting.The complete report is available at
