Project Description

This design-build project expanded the San Francisco Bay Area Rapid Transit District (BART) system 8 miles into San Mateo County from the existing Colma City station to the San Francisco International Airport (SFO) and terminating at the new Millbrae station.

The project route required that the northern portion of the line be placed underground using a cut-and-cover approach. The southern half of the alignment ran parallel to the Caltrain Corridor, which remained in active service throughout construction for freight and passenger traffic. Service to the airport was created by raising the BART line onto an elevated section that crossed the Caltrain Corridor and a sensitive wetlands area then connected to a Caltrans crossing of the US Highway 101, where it ties into an elevated station at the airport that is integrated with the airport people mover system (also built by Tutor Perini Corporation for SFO).
