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

A new transportation route is needed to provide a continuous north-south route through central Pinal County. The Arizona Department of Transportation (ADOT) and Federal Highway Administration (FHWA) are studying the area between U.S. Route 60 in Apache Junction and Interstate 10 near Eloy and Picacho. The purpose of the study is to identify and evaluate a possible route to provide a connection between these two areas.

This North-South Corridor Study will result in the preparation of a Location/Design Concept Report (L/DCR) and an Environmental Impact Statement (EIS) for a proposed 45-mile-long transportation corridor in Pinal County. In the fall of 2015, the extension of SR 24 was incorporated into the project. This addition combines the interrelated and previously distinct North-South Corridor Study and SR 24 extension projects into one integrated project. The NSCS will incorporate existing SR 24 study material, which began the evaluation of potential SR 24 extensions to the NSCS. There is an existing project being evaluated by ADOT to extend SR 24 to Ironwood Road; the NSCS will continue the study from Ironwood Road to the East.

The project will

  • relieve traffic on I-10.
  • provide an alternate route in the event of an I-10 incident.
  • 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.
  • address lack of capacity.
  • improve the efficiency of existing freeway and arterial street networks.
  • provide right of way to accommodate a passenger rail line between Tucson and Phoenix.

ADOT and FHWA are working with stakeholder agencies and the public to evaluate reasonable and feasible route alternatives and to prepare environmental documents and preliminary design plans for a phased implementation of the project.
