The State Transportation Board has approved a five-year transportation construction plan for 2024-2028 that includes funding to expand and improve the pavement condition of several highways critical to passenger travel and commerce.

The final version of the 5-year transportation construction plan for 2024-2028 is available at: azdot.gov/5 year program.

The program includes more than $9 billion in transportation investments, including $2.6 billion over five years in pavement improvement and bridge preservation projects throughout Arizona.

In addition, the program allocates funds for projects such as highway expansion and interchange improvements. These include:

Widening Interstate 10 between Phoenix and Casa Grande – currently estimated at just over $1 billion. This supports his ADOT goal of extending his I-10 to three lanes in each direction between Phoenix and Tucson. The first phase of construction on this corridor is the Gila River Bridge project, which is scheduled to begin later this year.

Construction of the Interstate 40/US 93 West Kingman Interchange. The program includes a total of $160 million for construction in 2024.

Expands and improves Interstate 93 in Wickenburg and Kingman, including widening three segments of the highway from two to four lanes. The 93 U.S. upgrades totaled $263.9 million and included widening projects near Cane Springs in 2024-2026, near Wickenburg in 2025-2026 and near Big Jim Wash in 2025-2027. be

Widening of 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, when he will complete his four-lane split highway along the entire SR 260 corridor.

Completed $40 million in pavement restoration statewide. This builds on the $50.5 million in pavement restoration projects already underway or to begin this summer, most of which are in northern Arizona. Governor Hobbs and the state legislature also allocated $54 million for additional pavement improvement projects in rural Arizona.

Public input is essential to updating the five-year construction plan each year, and this year is no exception. Additional or early planned projects based on feedback on the interim program include:

An 11-mile $35.8 million pavement restoration project on SR 260 through Pinetop Lakeside (added in FY27).

$13.9 million pavement restoration project on 4.5 miles of SR 90 in Sierra Vista (added in FY24).

Wikiup’s Gunsite Canyon Road to Gray Wash US93 16-mile $6.7 million pavement maintenance project (advance to current fiscal year ending June 30).

Other program highlights include $469 million in projects that improve highway safety, efficiency and functionality, such as adding smart technology and road shoulders. ADOT’s five-year program is developed by working closely with local governments and regional transportation planning agencies to prioritize projects that are ready for construction or design.

Funding for this program is primarily provided by users of transportation services through gasoline taxes, diesel fuel taxes and motor vehicle license taxes. Both Maricopa and Pima counties have established independent revenue streams through voter-approved sales tax increases, allowing for further expansion projects.
