Posted at 1:13 PM, Apr 04, 2024

TUCSON, Ariz. (KGUN) — The Arizona Department of Transportation (ADOT) is moving into the next phase of planning and design for its roughly 20-mile southerly link between I-10 and I-19, dubbed the 'Sonoran Corridor'.

ADOT is currently considering a route that will connect I-19 at El Toro Road to I-10 at Rita Road, bypassing the current interchange south of Tucson International Airport via routes along Alvernon Road and Old Vail Road.

During this next phase, which will include a Design Concept Report and Tier 2 Environmental Impact Statement, ADOT is looking to identify environmental concerns, more precise interchange locations and new design features.

You can access ADOT's Tier 1 Environmental Impact Statement online.

ADOT is welcoming comments and questions from the public via phone, email and mail.
