I-10 Reconstruction between Ruthrauff and Ina roads

Overview

The Arizona Department of Transportation and the Federal Highway Administration (FHWA) have recently completed a project that improved traffic flow and widened I-10 between the Ina Road and Ruthrauff Road interchanges in Tucson. Construction began in February 2023 and was completed in May 2026. A related Pima County project to extend Sunset Road between I-10 and River Road was constructed concurrently.

Key elements of the project included:

• 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
