Arizona is planning to spend $11.5 billion on statewide capital improvements to crucial transportation infrastructure through 2030.
The Arizona State Transportation Board recently approved the 2026-2030 Five-Year Transportation Facilities Construction Program, which emphasizes pavement and bridge improvements and expands several key highways.
The program features over $11 billion in transportation investments for roads, bridges and airports.
Funding for the statewide program comes from federal, state and local dollars in addition to money generated by users of transportation services in Arizona, primarily through gasoline and diesel fuel taxes and the Arizona vehicle license tax.
Transportation officials say the plan 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.
Projects include improvements to highway safety, efficiency and functionality, such as intersection improvements, updates to ports of entry and rest areas, smart technologies and new signals, signs and shoulders.
The five-year program also includes $135 million for the Airport Capital Improvement Program, which provides funding 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.
