Sonorah Corridor Study Map

When Arizona Department of Transportation engineers met with the community in Tucson and Sahuarita a month ago to talk about the proposed Sonoran Corridor, a mid-July deadline to comment at the start of a three-year environmental study must have seemed far in the future.

Don’t look now, but that deadline will be here before the weekend.

As with any important project, you will have more chances during the three-year study to let us know what you think about the proposed Sonoran Corridor, which would connect Interstate 10 and Interstate 19 south of Tucson International Airport. But now is the time to make your feelings known if you want your input included during this initial scoping phase.

Our first step will be to study a range of possible corridors for their potential social, economic and environmental impacts. If there’s a route through the study area that you like or don’t like, this is the time to share that with us so we can take your input or concerns into account as part of our study. In about three years, we’ll likely come back to discuss a possible route in more detail.

Under the Fixing America’s Surface Transportation (FAST) Act, the Sonoran Corridor has been designated as high-priority route that would support the economy of southern Arizona and the entire state while, relieving congestion at the interchange of I-10 and I-19 in downtown Tucson.

We want to hear from you before the deadline of Friday, July 14. Here’s how:

  • Complete an online comment form at
  • Visit to select any part of the study area that’s important to you, drop a virtual pin onto it and leave your comments. This interactive tool is available in Spanish too.
