TUCSON, Ariz. (KGUN) — Several Southern Arizona officials gathered at a ribbon-cutting Wednesday for the completion of the Sunset Interchange/Sunset Links project. Spearheaded by the Pima County Department of Transportation, the project extends Sunset Road from Interstate 10 to River Road. It is part of a 2006 voter-approved, RTA 20-year multi-modal plan that focuses on roadway and bridge improvements. The Sunset Links project hit delays last year due to the monsoon.
