Interstate 10: Ina Road Traffic Interchange Final Design

Project Description

I-10 currently passes over Ina Road, and with this project, Ina Road will become elevated and pass over I-10 and Union Pacific Railroad. The existing frontage roads and ramps will require reconstruction to intersect with the crossroad in its reconstructed (elevated) position.

The project includes two-lane, one-way frontage roads along each side of I-10 and necessary crossroad widening at the frontage road intersections and eliminate the existing at-grade railroad crossings of the Union Pacific Railroad tracks at Ina Road. The proposed improvements shown for I-10 meet the long-range planning objectives of ADOT, the town of Marana, Pima County, Pima Association of Governments and the RTA and improve the capacity, public safety and operational characteristics of the Ina Road TI. This project will also remain sensitive to environmental concerns and cultural resources.
