On June 16, 2017, the Arizona State Transportation Board approved an annual update to the Five-Year Transportation Facilities Construction Program of the Arizona Department of Transportation (ADOT), which includes projects in greater Arizona and the Maricopa County (Phoenix) and Pima County (Tucson) regions.
“Connectivity and reliability are crucial for an ever-expanding state highway system like Arizona’s, especially as the population continues to grow and businesses choose to relocate here,” ADOT director John Halikowski said. “Projects in ADOT’s Five-Year Construction Program will help move people, goods and services, generate commerce and economic activity through investments in major freight and travel corridors, and deliver on the agency’s commitment to not only maintain but improve the quality of pavement, bridges and other infrastructure.”
ADOT is able to accelerate some major expansion projects for greater Arizona because of federal funding increases, grants and state budget appropriations. Key commerce corridors like Interstate 10, State Route 189, US 93 and Interstate 17 will all see capacity improvements over the next five years. In addition, construction of a dust-detection and warning system along I-10 near Picacho Peak will move forward as part of the newly adopted program.
ADOT is also committed to protecting Arizona’s nearly $21 billion investment in the state highway system through dedicated preservation funding. The five-year program meets ADOT’s target of $260 million per year for preservation. Projects like repaving highways, repairing or reconstructing bridges, and projects to extend the life of existing pavement all help to preserve the highway system and keep it functioning as it should.
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. Both the Maricopa and Pima county regions have independent revenue streams established through voter-approved sales tax increases that allow for more expansion projects to take place.
