Ruthrauff Road closes at I-10 for interchange reconstruction

New bridge will carry Ruthrauff over I-10, railroad tracks in Tucson

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.

A new Ruthrauff Road bridge will open by fall 2021, allowing drivers to pass over I-10 and the railroad tracks. Ramps will connect Ruthrauff Road to the interstate by the end of 2021.

Work on the $129 million interchange began in January as part of the Regional Transportation Authority’s 20-year transportation plan. The Pima Association of Governments manages the RTA.

During the closure, drivers who normally use Ruthrauff Road can use Prince, Sunset or Orange Grove roads to access I-10. The interstate will remain open, with traffic shifted through the work during most of the project.

These restrictions and closures are now in place:

 Ruthrauff Road and El Camino del Cerro are closed to all traffic between HighwayDrive/Davis Avenue and the business entrances west of I-10.

 All ramps between I-10 and Ruthrauff Road/El Camino del Cerro are closed except forthe westbound I-10 off-ramp, which remains open to provide access to westbound I-10 frontage road businesses only.

 The eastbound frontage road is now a two-way road south of Sunset Road. There is noaccess to El Camino del Cerro from the frontage road.

 The eastbound frontage road is now a two-way road northwest of Commerce Drive. There is no access to or from El Camino del Cerro from the frontage road.

 The westbound frontage road is closed northwest of Prince Road.
