The Mid-Coast Corridor Project is a proposed extension of San Diego’s existing light rail infrastructure. Once completed, the Project would connect the Old Town Transit Center in downtown San Diego to the University City area to the north, via the Blue line trolley. This would connect several universities, hospitals, and technology companies to the city center.
The extension consists of 10.9 miles of additional double track as well as 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 transit vehicles. The Project will follow an existing commuter heavy-rail line and run parallel to the I-5 State Route 52 interchange.
