The Arizona Department of Transportation (ADOT) has approved the annual update to its Five-Year Transportation Facilities Construction Program after a three-month comment period.

“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 in an announcement. “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.”

Projects in Maricopa and Pima counties and greater Arizona were included in the plan. Some projects will be accelerated due to increased federal funding, grants and appropriations in the state budget. Interstate 10, State Route 189, US 93 and Interstate 17 are slated for expansion over the next five years. I-10 will also see the construction of a dust-detection and warning system near Picacho Peak.

ADOT will continue preservation projects, including repaving highways, bridge work and other projects to extend the usable life of existing pavement. ADOT allocated $260 million per year to preserve the highway system.

The five-year program is funded through gasoline and diesel fuel taxes and vehicle license taxes. In addition, Maricopa and Pima counties have voter-approved funding through sales tax increases.
