I-10 Reconstruction between Ruthrauff and Ina roads

Overview

The project to design improvements to Interstate 10 between the Ina Road and Ruthrauff Road interchanges in Pima County will include improvements to:

  • Reconstruct and widen approximately 2.5 miles of I-10 from three lanes in each direction to four lanes
  • Add auxiliary lanes to create two-lane entrance and exit ramps at all interchanges in this section of interstate
  • Remove existing inside shoulder pavement and construct additional lane in each direction near the Ina Road interchange
  • Reconstruct the traffic interchange at Orange Grove Road, including providing additional vertical clearance under I-10
 
  • Reconstruct the traffic interchange at Sunset Road to bring Sunset Road over I-10 
  • Reconstruct the Cañada del Oro Wash and Rillito River bridges to provide sufficient clearance
  • Construct retaining walls as needed throughout the project area
  • Provide drainage, lighting, landscaping and other improvements

Timeline

The design process began in December 2020. Construction is tentatively expected to begin in the second half of 2022.

Public Outreach

At least one public meeting will be scheduled during the design process to inform the public, businesses and stakeholders of the progress and provide an opportunity for input that will be considered before the design is final. The public information meeting is expected to be held in fall 2021.

Bicycle/Pedestrian Information

In connection with the improvements to Interstate 10 from Ina to Ruthrauff roads, there will be some construction activities for short periods in locations where the work will conflict with the safe use of The Chuck Huckelberry Loop (The Loop). ADOT is aware of how critical the I-10/Loop underpasses are for many bicyclists and pedestrians. It is anticipated that these activities during the construction phase will require temporary closures of The Loop where the path crosses beneath bridges spanning the Cañada del Oro Wash and the Rillito River, as well as where it meets both Orange Grove and Sunset roads. ADOT’s intention is to limit any closures of The Loop in those locations to less than 10 percent of the construction schedule in order to minimize impacts or inconvenience to users.

As the project design develops, ADOT will be able to provide more specific information about the construction phasing schedule and potential restrictions to The Loop.

Anyone who would like to receive informational alerts for bicyclists and pedestrians effects relevant to this project (or any other ADOT project in the area) are encouraged to sign up for notifications.
