Overview

The Arizona Department of Transportation, in partnership with the Federal Highway Administration and the Maricopa Association of Governments, is studying and designing preliminary concepts for improvements to the I-10 Broadway Curve area between I-17 (Split) and Loop 202 (Santan Freeway). The study team is conducting an Environmental Assessment in advance of making proposed improvements.

Proposed improvements include: adding general purpose and high occupancy vehicle lanes; adding a collector-distributor road system; substantially modifying the I-10/State Route 143/Broadway Road connections and the I-10/US 60 (Superstition Freeway) connection; improving drainage; constructing bridges;  improving the Intelligent Transportation Systems facilities; building retaining and sound walls and pedestrian bridge crossings; utility relocations; and other related work.

To obtain environmental clearance, ADOT will complete an Environmental Assessment guided by the National Environmental Policy Act of 1969 and federal and state environmental process requirements. Following the assessment of proposed alternatives and after public comments are received and considered, a determination of the significance of the impacts will be made. If no significant impacts associated with the proposed improvements are identified, the project will receive a Finding of No Significant Impact.

ADOT will provide information and ongoing opportunities for public input during the environmental study phase.
