North-South Segment 1, Tier 2 Environmental Impact Statement and Design Concept Report, U.S. 60 to Arizona Farms Road (State Route 505)

Overview

The Arizona Department of Transportation (ADOT) has formally initiated  a Tier 2 Environmental Impact Statement (EIS) and Design Concept Report (DCR) for the proposed North-South Corridor Segment 1 from US 60 to Arizona Farms Road (State Route 505). The study corridor spans approximately 20 miles from Apache Junction to Florence. The study will prepare a Tier 2 EIS and DCR to evaluate environmental and engineering considerations for potential alternatives for the proposed highway alignment and other features.

Public meetings were held in May to provide information on the study and preliminary alternatives being considered. The meeting presentation and materials are available below for those unable to attend a meeting.

The purpose of the North-South Corridor is to improve regional connectivity, provide an additional connection through a growing area of the Sun Corridor and address current and future transportation needs in Pinal County.

This study will:

• Refine the purpose and need of the proposed project
• Develop a preliminary range of alternatives for potential 400-foot-wide freeway alignments within the 1,500-foot Tier 1 study corridor that was selected in 2021
• Identify potential interchange locations and develop interchange design concepts
• Develop and circulate for public review and comment the draft Tier 2 EIS and DCR that compares the build alternatives against the No Build, or do nothing alternative, and identifies a Preferred Alternative based on engineering and environmental considerations, as well as agency, tribal government and public input
• Prepare final EIS and DCR documents identifying the Selected Alternative
