State Transportation Board Approves Five-Year Construction Program

The State Transportation Board has approved the 2024-2028 Five-Year Transportation Facilities Construction Program, which includes funding to expand and improve pavement conditions on multiple highways vital to moving passengers and commerce.

The final 2024-2028 Five-Year Transportation Facilities Construction Program is available at azdot.gov/FiveYearProgram.

The program, which includes more than $9 billion in transportation investments, commits $2.6 billion to upgrade pavement conditions and to work on bridge preservation projects across Arizona over five years.

Additionally, the program allocates funds for projects that widen highways or improve interchanges. These include:

• Widening Interstate 10 between Phoenix and Casa Grande – currently estimated at just over $1 billion. This supports ADOT’s goal of widening I-10 to three lanes in each direction between Phoenix and Tucson. The first stage of construction on the corridor is the Gila River Bridge project scheduled to start later this year.
• Constructing the Interstate 40/US 93 West Kingman Interchange. The program includes a total of $160 million for construction in 2024.
• 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 total $263.9 million and include widening projects near Cane Springs in 2024-2026, near Wickenburg in 2025-2026 and near Big Jim Wash in 2025-2027.
• Widening the last two-lane section of State Route 260 in the Lion Springs area. The program includes approximately $113 million for this improvement. Construction is scheduled for 2026-2027 and will complete a four-lane divided highway along the entire SR 260 corridor.
• Completing $40 million in pavement repairs statewide. This expands on $50.5 million in pavement repair projects already underway or starting this summer, most of them in northern Arizona. Governor Hobbs and the state Legislature also have allocated $54 million for additional pavement improvement projects in rural Arizona.

Public input is essential to annual updates to the Five-Year Construction Program, and this year’s is no exception. Projects added or planned sooner based on feedback on the tentative program include:

• A $35.8 million pavement rehabilitation project on 11 miles of SR 260 through Pinetop Lakeside (added for fiscal year 2027).
• A $13.9 million pavement rehabilitation project on 4.5 miles of SR 90 in Sierra Vista (added for fiscal 2024).
• A $6.7 million pavement preservation project on 10 miles of US 93 from Gunsite Canyon Road to Gray Wash in Wikieup (advanced to the current fiscal year ending June 30).

Other program highlights include $469 million for projects that improve highway safety, efficiency and functionality, such as smart technology or adding shoulders. 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.

Funding for the program is generated by users of transportation services, primarily through gasoline and diesel fuel taxes and the vehicle license tax. Both the Maricopa and Pima county regions have independent revenue streams established through voter-approved sales tax increases that allow for more expansion projects to take place.
