Corridor Profile Studies
Corridor Profile Studies
ADOT has developed a Corridor Profile Studies (CPS) program. The Statewide Map shows all the corridors that have been studied as part of the CPS program, with the corridors grouped according to how they were bundled during the latest updates made in 2022 and 2023.
The studies under this program provide a strategic vision for assessing the overall health of the state's primary highways, assisting the agency with performance-based project programming systems.
Corridor Profile Studies contain the following elements:
- inventory past project implementation proposals for each of the corridors.
- provide an overall assessment of the existing health of the corridor based on performance measures.
- propose various preliminary candidate solution sets to help improve overall corridor performance.
- recommend the most strategic preliminary improvements for the corridor.
