Interstate 10 and State Route 210 Feasibility Study

Study Timeline

The study has been divided into two phases. Phase I is complete and the final report is available on this project web page. Phase II is expected to be completed in early 2017.

Phase I: Feasibility Study and Environmental Overview

This phase of the study includes preparation of an engineering and environmental overview report for both Interstate 10 between the I-10/I-19 interchange on Tucson’s southwest side and SR 83 in eastern Pima County, and State Route 210 to a future connection with I-10 in southeast Tucson. View the final report.

Phase II: Design Concept Report and Environmental Assessment

This stage includes the preparation of a Design Concept Report and Environmental Assessment to comply with the National Environmental Policy Act for the future connection of State Route 210 with Interstate 10 in southeast Tucson. Work on the Phase II study will begin in summer 2015 and is expected to be completed by 2017.

A separate, but related, future study will evaluate potential future improvements on Interstate 10 between the junction with State Route 83 and the junction with State Route 90 in Cochise County, including environmental documentation.
