Grade Separation Update: Pile Driving on Pause Next Week

There will be no pile driving this week. Pile driving, which is the first step in the construction of the foundation of the grade separation, began in February. A total of 361 piles will be driven into the ground; more than 320 piles have been driven to date. 

Other work, which includes digging with a backhoe and mini-excavator will be done from 7 a.m. to 4 p.m. Temporary shoring will be installed in preparation for concrete pouring. Crews will locate and perform work on utilities. Gravel will be loaded and unloaded using medium duty diesel trucks. Crews will prepare foundations and pour concrete. 

Night work to prepare for the construction of the retaining walls will be done between 11 p.m. and 7 a.m., Monday, April 9 to Friday, April 13. 

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 between San Bruno and San Mateo Avenues will replace the station at Sylvan Avenue.
