Florence roundabout, pavement work also planned in southern Arizona

TUCSON – Major improvements are in the works for those who use Interstate 10 in the Tucson area, where new lanes and a rebuilt interchange are on track to open by the end of the coming year.

Motorists can expect a year of many changes as part of the ongoing project to widen I-10 between Ina and Ruthrauff roads. It’s one of several significant projects the Arizona Department of Transportation has planned for southern Arizona in 2024. 

Some highly visible progress on I-10 will begin early in the year as crews place 121 girders for nine new bridges, along with concrete paving for the rebuilt section of freeway.

And while heavy construction will dominate the 4-mile segment of I-10 during the year, it will come with a big payoff. By late 2024, ADOT will shift traffic onto a reconstructed freeway featuring four lanes of traffic in each direction. And the Orange Grove Road interchange will reopen with wider entrance and exit ramps to promote safety and better traffic flow.

The $171 million I-10 project will continue into 2025, when a reconstructed Sunset Road interchange opens. The interchange will feature a connection eastward to River Road thanks to a new bridge, funded by Pima County, that will carry traffic over the Union Pacific railroad tracks and the Rillito River.

Throughout the project, ADOT is maintaining three lanes of traffic through the work zone during daytime hours and maintaining access to businesses. The public can get project updates and traffic alerts at azdot.gov/i10ina2ruthrauff

Beyond Tucson, ADOT is planning projects to:

  • Repair the US 191 bridge over I-10 at milepost 131, about 9 miles west of Willcox. The work will include replacing the girders and deck following a crash that severely damaged the bridge in early 2023. Construction will begin in early 2024 and extend through the summer.

  • Construct dual roundabouts in Florence. The project includes a dual roundabout at State Route 287 and SR 79B in cooperation with the town of Florence and Maricopa Association of Governments. Nearby, ADOT will construct a single lane roundabout at SR 79B and Florence Heights Drive. The project is scheduled to be complete in summer 2024.

ADOT also has several pavement improvement projects planned in the coming year, including along 10 miles of I-10 near Casa Grande and 20 miles of SR 90 in and near Sierra Vista. For more information, please visit azdot.gov/projects
