North-South Corridor Study: Proposed New Transportation Route in Pinal County

A highway study in Pinal County that would improve regional connectivity, provide an additional way of getting around a growing area of the Sun Corridor, and address current and future transportation needs in a growing area is moving forward under a new environmental review process. The project scope also incorporates the extension of State Route 24 from Ironwood Drive to the North South Corridor. 

Currently, there are no funding options (including public-private partnerships) identified to build the proposed North South corridor. To continue and complete the project study with a federally approved National Environmental Policy Act (NEPA) action, The Federal Highway Administration and Arizona Department of Transportation have decided to transition the North South Corridor Study to a Tier 1 Environmental Impact Statement (EIS) from its current project-level EIS and will be utilizing the combined Tier 1 EIS and Record of Decision process to expedite the completion of the study.

This change allows the timing of final NEPA approval (Tier 2) to be more closely correlated with actual timing of project funding and construction as Tier 2 studies can be completed individually over time as construction funding becomes available.

The project will

  • address lack of capacity.
  • improve the efficiency of existing freeway and arterial street networks.
  • improve access to future activity centers.
  • enhance transportation system linkages.
  • create a more direct connection to the eastern portion of the Phoenix metropolitan area.
  • perform functions and provide services identified in local, regional and statewide plans.
  • evaluate potential multimodal facility (rail and utility) opportunities in the area.
