I-10

Girders over Santa Cruz River next week

It's one of two projects that will make the interstate three lanes in each direction between Tucson and Casa Grande.

Paving begins Monday, May 7

An Interstate 10 pavement-improvement project between State Route 587 (Casa Blanca Road) and the Gila River bridge south of Chandler will require overnight lane restrictions in both directions next week, April 16-19, according to the Arizona Department of Transportation.

Grubbing. Yeah, it's a real word. We looked it up. ADOT will be grubbing along I-10 in preparation for new lanes.

Second I-10 widening project in Pinal County

ADOT is widening Interstate 10 near Eloy, but motorists won't see much for delays during construction.

As a resident engineer, Kole Dea is responsible for administering construction projects and ensuring that every ADOT contractor follows engineering plans precisely.

A new bridge used only for construction will help expedite a project widening I-10 and creating a new interchange at SR 87.

After moving more than 450,000 cubic yards of earth, enough to fill up 150 Olympic-size swimming pools, construction on the Southern Avenue traffic interchange for the South Mountain Freeway remains on track to reopen Southern next month between 61st Avenue and 64th Place in Laveen.

On your next trip between Phoenix and Tucson, you'll see construction is underway on the project to widen I-10 and build a new interchange at SR 87 and Eloy.

Open house on Feb. 8

Changes are in store for motorists in the West Valley as multiple ramps leading to and from Interstate 10 will be permanently closed and reconfigured over the next several months to make room for an interchange connecting to the Loop 202 South Mountain Freeway

Construction activity on Pima County highways kicked off in 2018 with the bridge over Ina Road coming down and that's just beginning of improvements planned for the county over the coming years.

Major projects in Tucson in 2018

Come January, our focus will be on Pinal County in a big way.

Photos help tell the story of a freeway that will bring traffic relief when it opens by late 2019.

There's still a lot of accomplish in Tucson before ADOT crews ring in the new year.

MARANA – Drivers heading from northwest Pima County toward downtown Tucson will start using new eastbound lanes of Interstate 10 at Ina Road this weekend.

Beginning Saturday night, Dec. 16, Arizona Department of Transportation crews will begin moving eastbound traffic to the new lanes of I-10 as part of a two-year project to improve both I-10 and Ina Road. The work is expected to be complete the morning of Sunday, Dec. 17.

PICACHO – Crews will begin clearing ground near Interstate 10 south of Eloy this week as the Arizona Department of Transportation takes the first step in a project that will realign and widen 4 miles to three lanes in each direction.

The project also will create a first-in-in-the-nation pilot dust detection and warning zone designed to alert drivers to dangerous conditions in an area prone to blowing dust.
