Jerrold Avenue Bridge Replacement
Crews replaced the bridge over Jerrold Avenue in the City and County of San Francisco on Saturday, Oct. 15. The bridge was over 100 years old and reached the end of its useful life. Due to its age, the bridge deteriorated and no longer met modern state seismic safety requirements. It was replaced with new steel structures and support columns in order to keep Caltrain's bridge infrastructure in a state of good repair, which is critical in providing reliable and safe commuter rail service.
Crews removed three steel spans that composed the old Jerrold Avenue bridge and replaced it with a single span bridge. They also reconstructed the tracks on and adjacent to the new bridge structure.
Crews will now paint the new bridge structure, install a roadway drainage system for Jerrold Avenue and then repave and restripe the street.
During this time, Jerrold Avenue will temporarily be closed to through traffic between Rankin and Quint Streets. Originally set to open Nov. 5, the Jerrold Avenue closure period was extended to late December to allow more time to dismantle the old bridge.
