I-10

PHOENIX – An entirely new kind of traffic interchange for southern Arizona will start to take shape Monday, Aug. 24, as the Arizona Department of Transportation begins work on a project to improve access to Interstate 10 at Houghton Road.

Three ADOT projects from the last year have been recognized as some of the best in the industry in the 2020 America's Transportation Awards.

Interstate 10 drivers between Eloy and Picacho Peak should expect something very different this summer when storms hit: reduced speed limits, speed feedback signs and new overhead boards that display urgent safety messages.

PHOENIX – Visibility detectors. A weather radar system. Variable speed limit signs. Closed-circuit cameras. Overhead message boards.

These technologies clustered along 10 miles of Interstate 10 between Phoenix and Tucson are now operating as an innovative dust detection and warning system that’s ready to quickly tell drivers to slow down for safety when windblown dust reduces visibility.

We are four months into our project at I-10 and Ruthrauff. Check out this video of the work!

PHOENIX – Colossal Cave/Wentworth Road will close at Interstate 10 near Vail for about two months starting the night of Wednesday, May 27, for a bridge deck replacement project.

The Arizona Department of Transportation is taking advantage of lighter traffic during the current public health situation to complete the project ahead of schedule by replacing the entire deck at once rather than half at time. This approach allows major work on the project, which involves the bridge over eastbound I-10, to be completed in about two months rather than five months.

“Historians write the history, but balladeers bring it to life.”

So says Dolan Ellis, Arizona’s official state balladeer, who has spent more than 60 years bringing Arizona to life through song.

PHOENIX – Motorists who use Interstate 10 near Prince Road in northwest Tucson should plan for about one month of overnight lane restrictions because of a pavement maintenance project, according to the Arizona Department of Transportation. 

The project will begin Sunday, April 5, as crews seal concrete pavement joints on both directions of I-10. Work is scheduled Sundays through Thursdays, from 9 p.m. to 5 a.m.

We recently set to work demolishing the old I-10 bridge over Ruthrauff Road in Tucson to build a better interchange. 

Check out photos showing crews demolishing the eastbound I-10 bridge at Ruthrauff Road in Tucson to make way for a new interchange. 

PHOENIX – A day after crews moved eastbound Interstate 10 traffic off a bridge over Ruthrauff Road in northwest Tucson, crews have begun demolishing the structure as part of an Arizona Department of Transportation interchange replacement project.

PHOENIX – Motorists who use Interstate 10 between Phoenix and Casa Grande should plan for overnight lane restrictions through this fall because of a pavement improvement project, according to the Arizona Department of Transportation.

The project, scheduled to begin Sunday, March 22, will replace the pavement on both directions of I-10 between State Route 587 (Casa Blanca Road) at milepost 175 and SR 387 at milepost 185 near Casa Grande.

If your daily commute takes you along Interstate 10 in northwest Tucson, get ready to see some big changes to the highway’s configuration by the end of this weekend.

PHOENIX – Ruthrauff Road has closed at Interstate 10 in Tucson for nearly two years of construction on a modern interchange that will ease commutes and improve safety. 

I-10 exit and entrance ramps also are closed, with the exception of the westbound off-ramp, which remains open so motorists can access businesses along the frontage road.

Ruthauff Road remains open east of I-10, as does El Camino del Cerro west of the freeway. The Arizona Department of Transportation will maintain access to businesses near the workzone throughout the project.

PHOENIX – Over the weekend beginning the evening of Friday, Feb. 14, the Arizona Department of Transportation will close Ruthrauff Road at Interstate 10 for a two-year project to modernize the interchange serving a growing area of northwest Tucson.

ADOT will maintain access to area businesses throughout this project, which is creating a bridge carrying Ruthrauff Road over both I-10 and the Union Pacific Railroad tracks as well as widening the freeway.

As with other recent interchange projects, I-10 and Ruthrauff Road is getting a bridge carrying local traffic across the freeway and railroad tracks.  

PHOENIX – Though major restrictions aren’t set to begin until late winter or early spring, construction is set to begin Monday, Jan. 13, on an Arizona Department of Transportation project building a new interchange at Interstate 10 and Ruthrauff Road in northwest Tucson.

PHOENIX – When blowing dust reduces visibility along 10 miles of Interstate 10 between Eloy and Picacho Peak, a detection and warning system developed by the Arizona Department of Transportation will quickly tell drivers to reduce speed for safety.

However you add it up, the addition of two new lanes to I-10 between Picacho and Eloy is good news.

A proposal to make improvements to Interstate 10 at the Broadway Curve – the most-heavily traveled stretch of freeway in Arizona – is now available for public review and comment.
