San Bruno: Elevated Caltrain tracks take shape above downtown

Bay City News Service

SAN BRUNO -- A $147 million project to raise the Caltrain tracks 18 feet above three busy intersections in downtown San Bruno is about halfway completed, transit officials announced.

The San Bruno Grade Separation Project, which broke ground in November 2010, will elevate nearly a mile of Caltrain tracks above San Bruno, allowing multiple daily trains to pass safely above traffic and pedestrians on newly constructed bridges passing over intersections at San Bruno, San Mateo and Angus avenues.

Caltrain spokeswoman Christine Dunn said the change in downtown San Bruno is already dramatic, with bridges and support structures for the tracks reaching up into the skyline.

"I don't know if you've driven by in a while, but the change is dramatic," Dunn said. "You get a real sense of the project taking shape."

The reinforced concrete support structures sit atop a series of more than 300 steel pilings, some of which plunge more than 70 feet into the ground, Dunn said.

Given the busy nature of the location of the project, mitigating the effects of construction on traffic has been challenging, Dunn said.

The northern end of the project is adjacent to Interstate Highway 380, while the bridges are being constructed over San Bruno Avenue -- which connects to U.S. Highway 101 -- and San Mateo Avenue, which is one of the main surface streets that leads into to downtown San Bruno.

In addition, the new overhead tracks pass above BART's tracks to San Francisco International Airport.

Menawhile, Caltrain continues to operate 86 daily weekday trains through the area.
