I-10 Reconstruction between Ruthrauff and Ina roads

I-10 Reconstruction between Ruthrauff and Ina roads

Contents

Overview

The Arizona Department of Transportation and the Federal Highway Administration (FHWA) are working to improve safety and traffic flow on I-10 between the Ina Road and Ruthrauff Road interchanges in Tucson. A related Pima County project to extend Sunset Road between I-10 and River Road will be built at the same time.

Key elements of the project include:

  • Reconstructing and widening nearly four miles of I-10 from three lanes in each direction to four lanes
  • Adding auxiliary lanes to create two-lane entrance and exit ramps at all interchanges in this section of interstate
  • Replacing the existing inside shoulder pavement on I-10 to add an additional lane in each direction near the Ina Road interchange
  • Reconstructing the traffic interchange at Orange Grove Road, including providing additional vertical clearance under I-10
  • Reconstructing the Cañada del Oro Wash and Rillito River I-10 bridges to provide sufficient clearance
  • Constructing new bridges to carry Sunset Road traffic over the Union Pacific Railroad(UPRR) and the Rillito River
  • Constructing an access path to the Chuck Huckelberry Loop from Sunset Road

Additional work includes constructing bridges and retaining walls as needed throughout the project area and providing drainage, lighting, landscaping and other improvements. At the completion of the project, I-10 will have four travel lanes from 22nd Street to Ina Road.

Timeline

Construction is scheduled to begin February 2023 with completion expected at the end of 2025.

 

Traffic restrictions

Phase Two construction began in April and is scheduled to continue through fall 2024. During this phase, the following road restrictions are anticipated:

  • The Ruthrauff Road/El Camino del Cerro interchange, and the Ina Road interchange will remain open during construction.
  • Sunset Road will be closed between Silverbell Road and I-10 for the duration of the project as will the Sunset entrance and exit ramps.
  • The eastbound exit ramps and the westbound entrance ramp at Orange Grove will be closed until late 2024. Access to CalPortland will be maintained during construction via temporary entrance and exit ramps.
  • The westbound exit ramp to Orange Grove Road will be open, with the exception of a 50 day closure window expected to occur sometime in summer/fall of 2024.
  • River Road will be reduced to a single lane in each direction while the connection to Sunset Road is constructed.
  • The westbound frontage road will be closed near Sunset Road. It will be converted to a two-way road between the closure point and the Ruthrauff Road on-ramp to westbound I-10 (with no direct access back to Ruthrauff Road).
  • The eastbound frontage road will be closed near Walker Road. It will be converted to a two-way road between the closure point and the Ina Road on-ramp to eastbound I-10 (with no direct access back to Ina Road). Access to and from Walker Road will be maintained.
  • A temporary exit ramp on eastbound I-10 will provide access to businesses located on the eastbound frontage road between Sunset and Ruthrauff roads.
