Eastbound I-10 traffic switching to new lanes this weekend

I-10/Ruthrauff interchange reconstruction project nears halfway mark

New travel lanes of eastbound I-10

PHOENIX – Drivers heading from Marana toward downtown Tucson will begin using the new eastbound lanes of Interstate 10 at Ruthrauff Road this weekend.

Beginning Friday evening, Nov. 13, crews with the Arizona Department of Transportation will begin moving eastbound traffic to the new eastbound lanes as part of a nearly two-year project to rebuild the I-10/Ruthrauff Road interchange. The traffic shift is expected to be completed the morning of Saturday, Nov. 14.

The I-10/Ruthrauff Road interchange project, which remains on schedule and approaching the halfway point, will add a lane in each direction to I-10 and a bridge to carry Ruthrauff Road over the Union Pacific Railroad tracks. The improvements will allow traffic to move more smoothly through the area while enhancing safety.

Westbound I-10 traffic is tentatively scheduled to switch to the new eastbound pavement the night of Friday, Nov. 20.

ADOT will maintain three lanes of travel in each direction until the project is completed in late 2021. When the project is finished, I-10 will have four lanes in each direction and Ruthrauff/El Camino del Cerro will have two lanes in each direction. Also, reconstructed frontage roads will connect to the elevated interchange.

ADOT is overseeing the $129 million project, which began in early January. Ruthrauff/El Camino del Cerro will reopen across I-10 in summer 2021, with work continuing through the year to connect frontage roads and ramps. ADOT is maintaining access to area businesses throughout the project.

The project is part of the Regional Transportation Authority’s roadway improvement plan, managed by the Pima Association of Governments.
