San Bruno Grade Separation
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 at the site of the former San Bruno Lumber.With respect to pedestrian safety and amenities, the project will provide three pedestrian underpasses - one in the vicinity of Sylvan Avenue, one at the new station and another between Euclid Avenue and Walnut Street. Additionally, elevators will provide easy access for Caltrain customers. Streets and sidewalks, including those at Posy Park, also will be improved.
Day work will be done from 7 a.m. to 4 p.m. This week, crews will be painting, forming concrete for the ramp north of San Bruno Avenue, and forming concrete ramps and a water feature for Posy Park. Crews also will be using a tamping machine on top of the new structure, which lifts the tracks and ties into alignment, and compacts the ballast under and around the ties.
Night work will occur from Saturday, May 18, through Friday, May 24, between 8 p.m. to 6 a.m. Crews will be testing signals, and installing and lifting steel girders at San Bruno and San Mateo avenues on Saturday night into Sunday morning. Crews also will be using the tamping machine at night, in addition to generators, lights, forklifts and light trucks. There will be some construction noise, but crews will work as quietly as possible.
