Trolley Extension/Light Rail Transit


Construction start: October 2016

Expected start of service: 2021

A project of the San Diego Association of Governments (SANDAG), the Mid-Coast Corridor Transit Project is an 11-mile extension of the UC San Diego Blue Line Trolley service from Santa Fe Depot in Downtown San Diego north to University City. The Trolley extension will serve major activity centers, such as Old Town, UC San Diego and Westfield UTC.

Nine new Trolley stations will be built as part of the project with locations at: Tecolote Road, Clairemont Drive, Balboa Avenue, Nobel Drive, VA Medical Center, Pepper Canyon (UC San Diego west campus), Voigt Drive (UC San Diego east campus), Executive Drive and the Westfield UTC transit center (the Trolley’s terminus station).

Once completed, the Trolley extension will provide an effective campus commuting alternative, reduce roadway congestion, improve public transit services, and better connect the Mid-Coast Corridor with areas of San Diego County already served by existing Trolley routes.
