The Arizona Department of Transportation, in conjunction with the Federal Highway Administration and the Regional Transportation Authority, is evaluating improvements in two areas in the eastern Tucson area: Interstate 10 east of the I-10/I-19 interchange to State Route 83; and SR 210 (Barraza-Aviation Parkway) from Golf Links Road to a future connection with I-10 in southeast Tucson. The purpose of this study is to improve traffic flow on I-10 and to connect SR 210 with I-10.

The study has been divided into two phases and Phase One is currently in the final stages. A Final Report regarding Phase One will be available spring 2012.

Phase One - Feasibility Study and Environmental Overview: Includes preparation of an engineering and environmental overview report for both the I-10 east of the I-19/1-10 traffic interchange to SR 83 segment and SR 210 (Barraza-Aviation Parkway) to a future connection with I-10 in southeast Tucson.

Phase Two - Design Concept Report and Environmental Assessment: Includes preparation of a Design Concept Report and Environmental Assessment, to comply with the National Environmental Policy Act, for both the I-10 east of the I-10/I-19 interchange to SR 90 segment and SR 210 (Barraza-Aviation Parkway) to a future connection with I-10 in southeast Tucson. Phase Two is expected to begin sometime in 2012 and completed by 2014.
