PHOENIX – The State Transportation Board has approved the 2026-2030 Five-Year Transportation Facilities Construction Program, which emphasizes pavement and bridge improvements and expanding several key highways.

The $11.5 billion program was approved last week and meets the Arizona Department of Transportation’s goal of investing $2.4 billion in the next five years to preserve, rehabilitate and replace pavement and bridges on the state highway system, according to an ADOT release.

Greater Arizona expansion projects in the program include:

• Widening I-17 from Sunset Point to SR 69 starting in fiscal year 2028.
• Widening the Pinal County portion of State Route 347 between the City of Maricopa and Riggs Road starting in fiscal year 2027.
• Widening the Lion Springs section of State Route 260 east of Payson starting in fiscal year 2026.
• Widening US 93 north of Wickenburg along the Vista Royale segment starting in fiscal year 2026 and widening US 93 at Big Jim Wash between Wickenburg and Wikieup starting in fiscal year 2027.
• Building an interim road connecting a new commercial port of entry facility planned in Douglas with State Route 80 starting in fiscal year 2026.

In Maricopa County, the tentative five-year program lists expansion projects planned in conjunction with the Maricopa Association of Governments including:

• Widening Loop 303 from Lake Pleasant Parkway to 51st Avenue and improving the I-17/Loop 303 interchange starting in fiscal year 2026.
• Constructing State Route 30 from 97th Avenue to 71st Avenue starting in fiscal year 2030.
• Widening State Route 24 between Loop 202 and Ironwood Road in the Southeast Valley starting in fiscal year 2030.

The five-year program includes $135 million for the Airport Capital Improvement Program, which provides money in conjunction with the Federal Aviation Administration for projects "to design and construct safety, security and capacity enhancements, prepare various plans and studies, and fund improvements at the Grand Canyon National Park Airport," the ADOT release stated.

Funding for the overall statewide five-year construction 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, the Arizona vehicle license tax and various aviation taxes.
