Comment sought on engineering, environmental phase of study

PHOENIX – Members of the public have until Tuesday, June 10, to share comments about the engineering and environmental study for the North-South Corridor’s proposed northern segment spanning 20 miles between Apache Junction to Florence.

ADOT has been seeking public comment since work began in April on a Tier 2 Environmental Impact Statement (EIS) for Segment 1 of the North-South Corridor from US 60 to Arizona Farms Road. This phase will develop the purpose of and need for the proposed project, develop a preliminary range of alternatives for 400-foot-wide freeway alignments within the 1,500-foot corridor established in the Tier 1 Environmental Impact Statement, and review potential interchanges.

The corridor, also known as State Route 505, is under study to: enhance the area’s transportation network to accommodate the current and future population and employment growth; improve access to future development and other centers of activity; improve regional mobility; provide an alternative to and reduce congestion on Interstate 10; improve north-to-south connectivity; and integrate with the region’s transportation network.

ADOT’s outreach for this study included public meetings in May. Study presentations and materials are available at northsouth-segment1.com.

A separate study will be conducted for Segment 2 of the North-South Corridor between Florence and I-10 in Eloy.

Ultimately this study between Apache Junction and Florence will:

  • Recommend a preferred alternative for the project alignment, interchange locations and other features based on engineering and environmental considerations as well as agency and public input
  • Develop and circulate for public review and comment a draft Tier 2 Environmental Impact Statement and Design Concept Report that identifies the Recommended Build Alternative, which will be compared against the No Build, or do nothing, alternative
  • Prepare a final Environmental Impact Statement and Design Concept Report document identifying the Selected Alternative

Comments may be submitted in any of the following ways through June 10:
