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 $9B in transportation investments, commits $2.6B 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 more than $1B. 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 $160M 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 $263.9M and include widening projects near Cane Springs in 2024-2026, near Wickenburg in 2025-2026 and near Big Jim Wash in 2025-2027.
