San Bruno Grade Separation

Project Quality Assurance for Penninsula Corridor Joint Powers Board​

  • Elevate the Caltrain tracks above three existing at-grade street crossings

  • One new Caltrain station

  • Completion in 2013

  • Estimated construction $147 million

The $147 million San Bruno Grade Separation Project will elevate the Caltrain tracks above three existing at-grade street crossings at San Bruno, San Mateo and Angus avenues. This will improve safety for both motorists and pedestrians, and it will reduce traffic congestion to and from Highway 101 in the City of San Bruno.


In addition, a new elevated Caltrain station will be constructed between San Bruno and San Mateo avenues, replacing the existing station at Sylvan Avenue. A total of 201 parking spaces and a “kiss and ride” lot will serve the station.


With respect to pedestrian safety and amenities, the project will provide three pedestrian underpasses and elevators will provide easy access for Caltrain customers. Streets and sidewalks, including those at Posy Park, also will be improved.
