Loop 202 South Mountain Freeway

Project Overview

The proposed Loop 202 freeway, also known as the South Mountain Freeway, would run east and west along Pecos Road and then turn north between 55th and 63rd avenues, connecting with Interstate 10 on each end. A video simulation of the proposed freeway is provided below.

Project Update

The Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHWA) released the Final Environmental Impact Statement, or Final EIS, in September 2014. An addendum to the Final EIS, called an “Errata,” was published on Nov. 28, 2014. This document contains 10 additional comments to the Draft EIS that were inadvertently not recorded in the Final EIS and includes the responses to those comments.

The Final EIS formally documents the analysis of potential impacts associated with the preferred alternative, other action alternatives and the No-Action alternative, and proposes mitigation for all the action alternatives. The Final EIS also incorporates changes based on comments received and updated analysis based on new socioeconomic and traffic projections. Responses to public and agency comments on the Draft EIS can be found in Volume III of the Final EIS.
The South Mountain Freeway is the last piece to complete the Loop 202 and Loop 101 freeway system necessary for high-quality regional mobility.

The project has been a critical part of the Maricopa Association of Governments Regional Freeway Program since it was first included in funding through Proposition 300 approved by Maricopa County voters in 1985. The freeway was also part of the Regional Transportation Plan funding passed by Maricopa County voters in 2004 through Proposition 400.

In April 2013, the Draft Environmental Impact Statement (DEIS) was released for a 90-day review and comment period. A public hearing was held on May 21, 2013, at the Phoenix Convention Center, 100 N. Third St., Phoenix, AZ 85004. Representatives from ADOT, Federal Highway Administration (FHWA) and the technical team were on-hand to answer questions, and video and banners were available. In addition, an online public hearing site was created, which included the same materials presented at the physical public hearing location.

The comment period for the DEIS closed on July 24, 2013. ADOT, FHWA, and the study team reviewed over 8,000 comments submitted by the public, stakeholders and agencies during that 90-day period. All comments, regardless of how they were submitted, were considered and addressed in the FEIS, which was released on Sept. 26, 2014 for a 60-day review period. That review period has been extended to Dec. 29, 2014.
