Caltrain to install new bridge Oct. 15

Shortly after midnight, Saturday, Oct. 15, San Francisco's Caltrain will remove the railroad bridge that spans Jerrold Avenue in San Francisco and replace it with a modern single-span steel bridge. The "big move" will be accomplished in one night, before train service begins Saturday morning. The only impact to passengers will be at the Bayshore station, where all trains will operate on a single track and north and southbound passengers will board from a single platform all weekend. In addition to the new bridge, the project also includes new steel structures and columns to support the bridge, new tracks through the area, new pavement on the street under the bridge and new sidewalks. This week, crossing gates and lights on the adjacent freight train tracks will be temporarily removed, support frames will be constructed and the cranes that will be used to move the bridge will be mobilized. Jerrold Avenue has been temporarily closed to through traffic between Rankin and Quint Streets. This temporary closure will last until Nov. 5. The closed street is being used to assemble the new bridge and dismantle the old one. The project is necessary because the existing bridge is more than 100 years old and has reached the end of its useful life.
