Studies and Programs

Corridor Profile Studies

The Arizona Department of Transportation (ADOT) is conducting Corridor Profile Studies. The first three studies encompass the entire length of I-17, I-19 and I-40 from the California border to I-17. The second round of studies includes I-8 from California border to I-10, I-40 from I-17 to New Mexico, SR 95 from I-8 to I-40.  The third round of studies included I-10 East (SR 202 to New Mexico border), I-10/SR 85 (California State line to Junction I-8), SR 87/SR 260/ SR 377 (Junction SR 202L to Junction I-40), US 60/ US 70/ US 191 (US 60/US 70 (SR 79 to US 191) and US 191 entire length) and US 93/ US 60 (Nevada State line to SR 303L. Fourth round of Corridor Profile Studies are underway. Statewide map shows all the corridors that are being studied. The studies under this program will provide a strategic vision for assessing the overall health of the state's primary highways, assisting the agency with transitioning to a performance-based project programming system through targeted investments.

Statewide Summary Report

The Corridor Profile Study process is a comprehensive process to

  • inventory past project implementation proposals for each of the nine strategic corridors.
  • provide an overall assessment of the existing health of the corridor based on performance measures.
  • propose various solution sets to help improve overall corridor performance.
  • recommend the most strategic improvements for the corridor.

The goal of the Corridor Profile Study is to identify candidate projects for consideration in the Multimodal Planning Division's (MPD) Planning to Programming (P2P) project prioritization process providing information to guide corridor-specific project selection and programming decisions.

This new planning approach includes strategies and tools that incorporate life-cycle analysis and risk assessment to identify a range of cost-effective solutions for corridor deficiencies and prioritization of projects based on relative risks to operations, safety and performance. Studies will begin by identifying corridor needs and deficiencies. This process identifies the gap between system-performance rating goals and the existing or projected future performance. After identifying needs, life-cycle analyses and risk assessments will be used to evaluate a range of solution options and prioritize projects within the corridors. This information should be configured in a way that helps ADOT make risk-based decisions that inform the selection of cost-effective improvements for the short- and long-term planning and programming of corridor-specific projects statewide.
