I-10 Reconstruction between Ruthrauff and Ina roads


The Arizona Department of Transportation and Federal Highway Administration are completing final design on a project to improve to Interstate 10 between the Ina Road and Ruthrauff Road interchanges. ADOT will also oversee construction of a related Pima County project to extend Sunset Road between I-10 and River Road that will be built along with the I-10 project by a single contractor.

Key elements of the combined projects 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 I-10
  • 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 learance
  • Reconstructing the traffic interchange at Sunset Road to bring Sunset Road over I-10 
  • 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
