I-10

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

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.

The Ina Road interchange was progressing without any surprises until a furry visitor make an unexpected appearance.

MARANA – Over the next three months, drivers in northwestern Pima County will see important advances as the two-year Interstate 10/Ina Road traffic interchange project moves on schedule toward the halfway point.

With pavement now in place for what will become the eastbound lanes of Interstate 10 at Ina Road, crews will begin steps to move traffic to those new lanes so work can begin on the westbound lanes of I-10.

PHOENIX ‒ The Sacaton Rest Area on Interstate 10 south of the Phoenix area is scheduled to close Wednesday, Oct. 18, for a $4 million renovation that’s expected to take six months, according to the Arizona Department of Transportation.

Work planned for the rest area, located on both westbound and eastbound I-10 between Casa Blanca Road and State Route 387 near Casa Grande, includes upgrades to comply with the Americans with Disabilities Act, replacing a water line, replacing the septic tanks and sewer lines, upgrading the electrical and mechanical systems, and painting.

GOODYEAR – Major work on the freeway interchange connecting Interstate 10 and Loop 303 in the West Valley has been completed.

The Arizona Department of Transportation has now opened all four of the new ramps that allow drivers to make direct connections between I-10 and Loop 303. Three ramps were opened to traffic Sunday night, Oct. 8. Construction crews on Monday opened the fourth ramp, which connects westbound I-10 to southbound Loop 303.

A new section of Loop 303 traveling under I-10 between Thomas Road and Van Buren Street in Goodyear also is open to traffic.

At the sixth-month point of the Ina Road/I-10 project, several things should catch your eye.

MARANA – Six months in, signs of progress abound at an Arizona Department of Transportation project creating a modern traffic interchange at Ina Road and Interstate 10 and more efficient traffic flow through a growing area.

Crews recently poured concrete to create a deck for the first of two new bridges carrying Ina Road over the Santa Cruz River just west of I-10.

Frontage-road construction rarely gets attention within a larger freeway project, but that isn't the case with work underway in Goodyear.

GOODYEAR – Crews working to build the last phase of the Loop 303/Interstate 10 traffic interchange in Goodyear have reached another milestone.

New stretches of separate north- and southbound Loop 303 frontage roads between McDowell Road and Van Buren Street opened to traffic as scheduled on Saturday, Aug. 19, according to the Arizona Department of Transportation.

PHOENIX – A pavement-improvement project along Interstate 10 between the Gila River Bridge and State Route 587 (Casa Blanca Road) will require overnight lane restrictions and some ramp closures starting Sunday night, Aug. 20, according to the Arizona Department of Transportation.

Drivers should allow extra travel time and consider alternate routes if possible while the following restrictions are in place the week of Aug. 20-25:

There's a lot to see and a lot happening at I-10 and 59th Avenue in west Phoenix, where an interchange under construction will link with the South Mountain Freeway.
