I-11

The Arizona Department of Transportation submitted a competitive grant bid that, if awarded, would allocate approximately $65 million to speed up already-planned improvement projects on US 93 between Wickenburg and Interstate 40. 

If the grant application is approved, these competitive funds would be added to state match funding and additional federal dollars, for a potential total of more than $200 million for the improvements on US 93, in partnership with the Federal Highway Administration.

We've already widened 161 miles of US 93, the main route between Phoenix and Las Vegas, to divided four-lane highway. Now we're launching a project to widen nearly 4 more miles.

We're conducting two environmental studies involving southern Arizona: Interstate 11 and the Sonoran Corridor. Here's an explanation of each.

After investing more than half a billion dollars over the past 20 years to turn the primary route between Phoenix and Las Vegas into a modern four-lane divided highway, the Arizona Department of Transportation has committed another $155 million for improvements to US 93 over the next five years.

PHOENIX – After months of technical analysis that includes the results of public, agency and tribal input gathered earlier this year, the Arizona Department of Transportation, in partnership with the Federal Highway Administration, has published two key documents as part of the environmental study for Interstate 11 from Nogales to Wickenburg.

Year one of the I-11 study is over. Our newest video provides a recap of what's been done to date and explains what's next for the proposed interstate.

Now is the time to participate in I-11 corridor alternative meetings and share your thoughts on the proposed interstate!

A new I-11 video has launched and we're inviting the public to meetings to comment on the proposed corridors.

PHOENIX – As the Interstate 11 environmental study progresses and new proposed corridor alternatives have taken shape, the Arizona Department of Transportation is once again looking to the public and agencies to get involved and comment on the work that’s been done over the past year.

Six public meetings have been scheduled in May as part of ADOT’s commitment to study and get input on a 280-mile-long corridor stretching from Nogales to Wickenburg.

PHOENIX – Over the past year, the Arizona Department of Transportation asked the public and agencies to share their ideas, comments and concerns about the Interstate 11 environmental study from Nogales to Wickenburg. A summary of comments is now available and will help ADOT select and evaluate corridor alternatives for further study.

With a three-year environmental study that began recently for an I-11 corridor between Nogales and Wickenburg, here’s a quick rundown of who’s involved.

PHOENIX – The numbers speak volumes about Arizona’s interest in the proposed Interstate 11: Six public meetings held recently attracted 540 community members who shared comments and questions. Hundreds more offered their perspectives online.

The Arizona Department of Transportation’s Interstate 11 study team visited Casa Grande, Buckeye, Nogales, Tucson, Marana and Wickenburg to involve the community in a process known as public scoping, part of an environmental study to select a corridor alternative between Nogales and Wickenburg.

Continued investment in our state’s busiest corridors and those beyond our state borders will provide better mobility and help enhance economic development.

There is still time to comment on the Interstate 11 environmental study.
