Interstate 10 and State Route 210 Feasibility Study

The Arizona Department of Transportation, in conjunction with the Federal Highway Administration and the Regional Transportation Authority, is completing a two-phase study in the Tucson area and southeastern Arizona. The first phase, which was completed in 2015, evaluated potential future improvements for Interstate 10 between the junction with Interstate 19 and the junction with State Route 83, as well as State Route 210 (Barraza-Aviation Parkway) from Golf Links Road to a yet-to-be-determined future connection with I-10 in southeast Tucson.

The second phase, which is expected to be completed in February 2015, will evaluate in more detail potential alternative locations where SR 210 will connect with I-10.
