Maricopa County projects total $2 billion of Arizona's $8.2 billion transportation program


The State Transportation Board has approved its 2025-29 five-year construction program, which focuses on improving pavements and bridges and expanding several highways.

In Maricopa County, the program includes approximately $2 billion in construction projects planned in partnership with the Maricopa Association of Governments. The projects include:

The $8.2 billion program “places a strong emphasis on improving highway pavements and bridge infrastructure throughout the greater Arizona metropolitan area, including areas outside of Maricopa and Pima counties,” according to a press release from the Arizona Department of Transportation.

The plan allocates more than $2.5 billion over the next five years for “high-priority improvements,” an average investment of $500 million per year “to maintain, rehabilitate and replace pavements and bridges,” the press release said.

The program provides a total of $800 million over five years for projects that transportation officials say will improve safety and efficiency on highways, such as intersection improvements, smart technology, freight mobility, and signs, signals and lighting.

In addition, $780 million will be allocated for projects that widen highways or improve interchanges in the greater Arizona area, including:

  • Widening and improvements to US 93 between Wickenburg and I-40 in Kingman, including widening three sections of the highway from two to four lanes. Improvements to US 93 include the ongoing widening project near Wickenburg, as well as new projects near Cane Springs, Vista Royale and Big Jim Wash.
  • Widening the last two-lane section of State Route 260 in the Lion Springs area between Payson and Heber-Overgaard. This will complete a four-lane highway along the entire SR 260 corridor.
  • Construction of a new I-40 interchange at Rancho Santa Fe Parkway in Kingman.
