Mission Valley Light Rail (West)

Cost:$62 million
Client:Metropolitan Transit Development Board
Location:San Diego, CA
Markets:Rail Transit

The west section of the Mission Valley Light Rail Transit system in San Diego encompassed over three miles of tracks, including 1.5 miles of elevated track. Significant features include new main light rail tracks with traction power and catenary systems, two at-grade stations, one elevated station, and a bus transfer facility. The elevated station includes an elevator and two pedestrian bridges which allow access to the upper station.

The project involved significant roadway reconstruction and utility work, including a $5 million sewer relocation. To preserve an archaeologically sensitive area containing Native American artifacts, a 1,200-foot tunnel was constructed to encase the 78-inch sewer line designed to run through the site.

The 30-month project schedule was critical, and all work had to be completed so the transit line could open for the 1998 Super Bowl held at Qualcom Stadium. Complicating the job further, environmentally sensitive areas and the mall parking lot bound the site, so construction was performed in a very narrow corridor.
