The Mid-Coast Corridor project is a 10.9-mile extension of San Diego's existing light rail infrastructure. Once completed, the project will connect the Old Town Transit Center in downtown San Diego to the University City area to the north, via the Blue Line trolley, and serve major activity centers including Old Town, the University of California, San Diego, and the Westfield UTC shopping center. The route will connect several universities, hospitals, and technology companies to the city center. Currently, University City and UC San Diego, two of the region's largest trip generators, are not served directly by regional transit services.

The double track extension also includes nine new stations (four at-grade and five elevated), five park-and-ride facilities with 1,070 spaces, 14 new and two upgraded traction power substations, and 36 new low-floor light rail transit vehicles. The project will follow an existing commuter heavy-rail line and run parallel to I-5.

  • The Mid-Coast Corridor is among the TransNet local revenue measure's Early Action Projects. The availability of the TransNet funding is accelerating the completion of these projects over a 40-year program period beginning in 2008. SANDAG and its local partners retained five consultant teams for 5-year, $10 million design and construction management on-call contracts to oversee the completion of the program. Tasks performed under these on-call contracts can include program management and the development of roadway, structure, and transit projects.
