Arizona’s State Transportation Board has approved the 2023-2027 Five-Year Transportation Facilities Construction Program, which includes several highway expansion and improvement initiatives.
The $571 million allocation would address projects widening highways or improving interchanges focusing on, among other efforts, adding lanes along Interstate 17 between Anthem Way and Sunset Point; two projects to begin widening Interstate 10 between Phoenix and Casa Grande; constructing the first phase of the I-40 / US 93 West Kingman interchange; and widening the last two-lane section of State Route 260 in the Lion Springs area.
The I-17 and I-10 widening projects advance via the Arizona Department of Transportation’s (ADOT) partnership with the Maricopa Association of Governments, which has committed some of the funds for the improvements.
Major projects begin as part of the State Transportation Board’s long-range visioning process. There is a transition into a six- to 10-year development program before becoming part of the Five-Year Program.
The State Transportation Board collaborates with local and regional planning organizations, as well as community leaders to identify projects ready to build or design, according to officials, adding funding for the Five-Year Program is generated by the users of transportation services, primarily through gasoline and diesel fuel taxes and the vehicle license tax.
