ADOT selects final North-South Corridor route in Pinal County

Following several years of study, technical analysis and input from communities and stakeholders, the Arizona Department of Transportation has selected a final 55-mile North-South Corridor through Pinal County. The Final Tier 1 Environmental Impact Statement (EIS) and Record of Decision (ROD), which was released today, identifies the selected corridor, which stretches from the U.S. 60 in Apache Junction to Interstate 10 in Eloy in Pinal County. The study also incorporates a proposed extension of State Route 24 from Ironwood Drive to the North-South Corridor.

The Final Tier 1 EIS is available on the ADOT website and at repository locations throughout the study area. Because the Record of Decision is the final decision-making document for the Tier 1 study, there is no formal comment period for the Final Tier 1 EIS and ROD.

A continuous, access-controlled north-to-south transportation corridor would:
• Improve access to future activity centers
• Improve regional mobility
• Improve north-to-south connectivity
• Integrate the region’s transportation network
• Address existing and future population and employment growth
• Provide an alternative to avoid congestion on I-10

The Final Tier 1 EIS, conducted in accordance with the National Environmental Policy Act (NEPA), incorporates changes based on comments received on the Draft Tier 1 EIS, as well as updated analyses based on new information. The Draft Tier 1 EIS was published on Sept. 6, 2019 and made available for review and comment from Sept. 6 through Oct. 29, 2019, with public hearings held in October 2019.

The Draft Tier 1 EIS evaluated the potential short- and long-term impacts associated with a range of Corridor Alternatives, including the No-Build Alternative, and recommended a Preferred Corridor Alternative. The Corridor Alternatives were developed based on input from the public; coordination with local, regional, state and federal agencies and tribes; and findings from previously completed studies.

The identification of the Preferred Corridor Alternative in the Draft Tier 1 EIS was based on how well it met the purpose and need while reducing the potential for adverse impacts.
