The San Bruno Station is part of the planned Bay Area Rapid Transit District SFO Extension. This station provides a single platform below grade to serve 2 BART tracks, a concourse at grade, and an open air roof structure above. The Tanforan Shopping Mall is immediately adjacent to the San Bruno Station.

The main architectural feature of the station structure is the manner in which the concourse is configured to permit natural light to illuminate the underground platform, thereby providing the illusion of an "open air" station. Another key feature of the design are the "delta-truss" frames used to support the vaulted roof structures and resist lateral loads. The platform is 700 feet long, the concourse is 350 feet by 70 feet, and the roof is 350 feet by 50 feet.

OPAC Consulting Engineers prepared the structural design for this design-built project, a first for the Bay Area Rapid Transit District. Greg Roja and Associates, Inc. prepared the architectural design.
