ADOT Selects final Sonoran Corridor route in Pima County Sonoran Corridor Tier 1 Final Environmental Impact Statement and Record of Decision

Following several years of study, technical analysis and input from communities and stakeholders, the Arizona Department of Transportation has selected a final 20.47 mile corridor through Pima County. The Final Tier 1 Environmental Impact Statement (EIS) and Record of Decision (ROD), which was released Friday, Nov. 5, identifies the selected corridor, which stretches between Interstates 19 and 10, south of the Tucson International Airport in Pima County.  A continuous, access-controlled transportation corridor between I-19 and I-10 would: Improve access to future activity centers Improve regional mobility Improve connectivity Integrate the region’s transportation network Address existing and future population and economic growth Provide an alternative to avoid congestion on I-10 and I-19  The combined Tier 1 Final EIS/ROD, along with its supporting documentation, is available on the study’s website at azdot.gov/Sonoran Corridor.   In addition, hard copies of the combined Tier 1 Final EIS/ROD document are also available for viewing at the following locations during normal business hours: Southcentral District Office - 1221 S. 2nd St. Tucson.

The phased implementation plan includes smaller segments of the selected corridor alternative that may advance as separate, independent projects. These studies, which are not yet funded, would include additional analysis and more opportunities for public review and comment.
