FirmoGraphs keeps its clients up to date on Statewide Transportation Improvement Programs (STIPs) of interest for long-term business development. We help our customers use this information to gain a competitive advantage and improve proactive conversations with their clients. We recently processed the latest transportation improvement program from the State of Arizona. Here are the insights we observed. 

In the STIP covering the 2022-2026 fiscal years, the State of Arizona Department of Transportation (DOT) detailed plans to spend nearly $8.3 billion on transportation projects, increasing 6.8% from $7.7 billion in the 2021-2025 STIP. The current STIP has 1,127 discrete projects, compared to 1,045 projects in the prior STIP. The table below breaks down the State of Arizona DOT's planned capital spending by business area (counties) for its last two STIPs.

*Numbers are Rounded

Most Notable Spending Increase in Pima County, Decrease in Maricopa and Coconino Counties

Planned spending in Pima county increased by 46.5% to $1.7 billion. The $533.6 million increase goes to existing projects. The Tucson International Airport (TUS) Near Parallel Highway project increased by $212.8 million to relocate the Runaway 11R/29L and associated taxiways. New projects in the Statewide category include $91.7 million for bridge preservation, replacement, and rehabilitation and $64 million for pavement preservation. Additionally, $57.1 million is intended for the Development Support Highway Safety Improvement Program (HSIP), which would involve various local projects awarded through a competitive HSIP application process.


The Maricopa and Coconino category cut their spending by 11.7% and 45.9%. The decrease in Maricopa county is due to the existing projects that will be completed in 2022. That includes I-17 SPLIT - SR-202L Santan (Near-Term Improvement Strategy) project worth $349.8 million and the Anthem Way TI- Cordes Junction project worth $83.6 million. For Coconino county, there are 48 completed projects. The largest completed is the High-Capacity Transit Route-Engineering and Environmental project, worth $27 million.

Maricopa County Projects Still Receive Substantial Investments

Arizona's recent STIP has 13 projects valued at more than $100 million and 54 projects valued at more than $25 million. The Statewide category has the largest single project, Pavement Rehabilitation project, worth $665 million. 

Although the Statewide category has the most valued project, most projects valued at more than $100 million are in Maricopa county. The biggest ones are as follows:

  •  $380.9 million for SR 30, TRES RIOS project;
  • $349.8 million for I-17 SPLIT-SR-202L Santan (Near-Term Improvement Strategy) project;
  • $227.4 million for the I-10 Papago System Interchange Improvements project and;
