SR-30 (Tres Rios Freeway), SR 202L to I-17 Scoping Study


MAG, in partnership with the Federal Highway Administration (FHWA) and Arizona Department of Transportation (ADOT), is developing a scoping study for a section (Durango Link) of the proposed State Route 30 (SR-30, Tres Rios Freeway). This segment will ultimately connect the Loop 202 South Mountain Freeway (currently under construction) near 59th Avenue to I-17 near the Durango curve. The study will recommend a corridor for this segment of the SR-30 and other improvements that may be incorporated into a future Regional Transportation Plan.

The SR-30 scoping study is following the Planning and Environmental Linkages (PEL) process developed by FHWA and adopted by ADOT. The goal is to integrate early planning efforts with the National Environmental Policy Act (NEPA) process for a project that would become part of the RTP and TIP based on the results of this study. This study complies with regulations at 23 Code of Federal Regulations (CFR) § 450.212 concerning linking planning studies with NEPA. The PEL process allows the following types of long-range planning and environmental analyses to inform the preparation of a future NEPA document:

  • Project purpose and need, including planning goals
  • Public and stakeholder issues
  • Agency issues (federal, state, local and tribal)
  • Description of the existing environmental setting
  • Identification of general travel modes
  • Preliminary screening of alternatives and elimination of unreasonable alternatives
  • Recommendations for future projects

There are currently no upcoming events for SR-30 (Tres Rios Freeway), SR 202L to I-17 Scoping Study
