Background - I-10: Ina Road Traffic Interchange Construction

Draft Environmental Assessment Re-Evaluation

The Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHWA) are proposing to reconstruct the Interstate 10 / Ina Road traffic interchange and make improvements to Ina Road between Silverbell Road and Camino de la Cruz. The project will enhance safety by eliminating the existing at grade crossing of Ina Road and the Union Pacific Railroad (UPRR) and building an overpass taking Ina Road over I-10. I-10 will be lowered as part of the new Ina Road overpass construction. The project will also construct two structures over the Santa Cruz River. The eastbound and westbound frontage roads will be elevated to intersect with the new vertical alignment of Ina Road. The Loop Trail would be closed at Ina Road for extended periods during the project construction period.
