North-South Corridor

ADOT’s Preferred Corridor Alternative is till 25 years away unless Pinal County’s transportation excise tax survives a court challenge, and local jurisdictions begin building it right away.

PHOENIX — The Arizona Department of Transportation is issuing the final call for comments on the Pinal County North-South Corridor Draft Tier 1 Environmental Impact Statement.

The comment period began on Sept. 6 and closes at 5 p.m. Tuesday.

During the comment period, ADOT has held three public hearings in Florence, Eloy and San Tan Valley.

The proposed North-South Corridor is for a 50-mile highway in Pinal County that would stretch from U.S. 60 in Apache Junction to Interstate 10 near Eloy.

It would also connect to State Route 24 in Queen Creek.

The entire Draft Tier 1 Environmental Impact Statement, along with all public involvement materials provided at the public hearings, is available at

An online comment form is also available to the public on the study website.

All comments and questions will be documented and answered by ADOT in the Final Tier 1 Environmental Impact Statement, which is expected to be complete in 2020.

Prepared by ADOT, the study process is to be completed in compliance with the National Environmental Policy Act.

It proposes a Preferred Corridor Alternative, including a parallel analysis of a No-Build Alternative.

The Preferred Corridor Alternative is 1,500 feet wide and includes an area where construction of a freeway could be further analyzed.

If a corridor is selected at the end of the Tier 1 study, further Tier 2 studies and evaluations must take place before construction could be considered.

The corridor would be narrowed to a highway alignment, which is about 400 feet wide.

An alignment determining where the North-South freeway could potentially be built would be decided during a future phase of design and environmental studies.

There currently are no plans or funding available to initiate these Tier 2 studies.

Anyone can submit comments on the Draft Tier 1 Environmental Impact Statement through Tuesday using the following methods.
