The public comment period for the FY 2024-2028 Tentative Five-Year Transportation Facilities Construction Program ends at 5 p.m. Thursday, June 1. 

The tentative program includes an investment of $2.6 billion in pavement and bridge preservation projects across Arizona over five years. 

The $7.7 billion tentative program also proposes allocating $669 million for projects that widen highways or improve interchanges. Those projects include:

• Widening Interstate 17 north of Phoenix from Anthem Way to Black Canyon City, plus adding flex lanes from Black Canyon City to Sunset Point. The five-year program contains $83.6 million toward work that is underway for a total project cost of $502.7 million.

• Widening the Gila River bridges between Phoenix and Casa Grande. The program dedicates $50 million toward the project in 2023 and is a key step toward ADOT’s goal of widening I-10 to three lanes in each direction between Phoenix and Tucson.

• Constructing the first phase of the I-40/US 93 West Kingman interchange. The program includes a total of $160 million for construction in 2024 and 2025.

• 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, near Wickenburg in 2026 and another widening project near Big Jim Wash in 2027.

• Widening the last two-lane section of State Route 260 in the Lion Springs area. The program includes $125 million for construction in 2026 and would complete ADOT’s goal of completing a four-lane divided highway along the entire SR 260 corridor.

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. The State Transportation Board is expected to consider formal action on the program at its June 16 meeting.
