SANDAG – Midcoast Trolley Expansion

Project Synopsis
CPM Partners is providing a wide breadth of construction management support for SANDAG’s Mid-Coast Transit Corridor Program.

The Mid-Coast Corridor Transit Project will extend the Trolley Blue Line service from the Santa Fe Depot in Downtown San Diego north to the University City community, serving major activity centers such as Old Town, the University of California, San Diego (UCSD), and Westfield UTC.

The Trolley extension route begins just north of the Old Town Transit Center and travels in existing railroad right-of-way and alongside Interstate 5 to serve UCSD and University City. The 11-mile (3.3 miles of elevated viaduct) extension will serve nine new stations: Tecolote Road, Clairemont Drive, Balboa Avenue, Nobel Drive, VA Medical Center, Pepper Canyon (serving UCSD west campus), Voigt Drive (serving UCSD east campus), Executive Drive, and the terminus station at the Westfield UTC transit center.

The program also includes two LOSSAN projects; the San Diego River Double Track (SDRDT) project and the Elvira to Morena Double Track (EMDT) project. The SDRDT involves the addition of 0.9 miles of second main track between CP Tecolote and CP Friar. The project includes double tracking across the San Diego River with a new double track bridge, construction of associated site improvements, and signal modifications. The EMDT project will add a 2.6-mile second main track from State Route 52 to just south of Balboa Avenue. the project includes replacement of three existing single-track bridges with new bridges to accommodate double track operations, signal improvements, and ancillary utility and drainage improvements.
