Study Update: November 1, 2017
In 2013, ADOT and the Federal Highway Administration (FHWA) reinitiated the study of Loop 303 south of Van Buren Street to SR 30. The project team continues to work on the Environmental Assessment (EA) and Design Concept Report (DCR). Draft documents are scheduled to be released to the public and posted on this website in spring 2018; at that time a public hearing will be scheduled. If you would like to be notified via email when the Draft Environmental Assessment is available for review and the hearing is scheduled, please subscribe to the Loop 303 South email notification. The hearing will be your opportunity to provide feedback on the project and on the EA and DCR.
Construction of Loop 303 south, between I-10 and Van Buren Street, began in February 2016 and was completed in October 2017. Although the initial construction extended Loop 303 south to Van Buren Street, the study plans for the continued southerly extension of Loop 303 to the proposed SR 30 south of MC 85.
The next segment of Loop 303, Van Buren Street to MC 85, is scheduled to begin final design in the Fall of 2018 and begin construction after the of Summer 2020.
Throughout its length, Loop 303 has been planned to accommodate an ultimate configuration of four general-purpose lanes and one high-occupancy vehicle (carpool) lane in each direction.
