Grade Separation Update: Construction Will Pause for Thanksgiving

Work on the grade separation project will take place during the week, from Saturday, Nov. 19 to Wednesday, Nov. 23. 

Day work will take place between the hours of 7 a.m. and 5 p.m. This work will include removing and installing traffic signs, upgrading signal systems, installing and removing fences along the right-of-way, grading for the shoofly, roadway striping, installing crossing gates at Angus Avenue, track work, and water line and sanitary sewer relocations. Motorists should expect delays. Relocation of water lines and sanitary sewers will primarily occur at Angus and Huntington avenues and may require temporary lane closures. Traffic cones and flaggers will direct motorists and pedestrians around the affected areas. 

Night work will take place from 8 p.m. to 7 a.m., outside of peak passenger service hours. This work will include upgrading signal system and relocating communication utilities. Demolishing the former station must occur at night so as not to disrupt train service and also to protect the safety of construction workers given the close proximity to tracks. Digging work will require the use of a backhoe, mini-excavator and jackhammer. At times, noise levels could be as high as 75 decibels. Crews will use generators to power portable light towers. Night work will be done in accordance with Caltrain and city agreements and ordinances.

The $147 million project will elevate the Caltrain tracks above three existing at-grade street crossings at San Bruno, San Mateo and Angus avenues. A new elevated Caltrain station will be constructed between San Bruno and San Mateo avenues, replacing the existing station at Sylvan Avenue.
