Scope & Need
Caltrain will remove and replace the existing vehicular/pedestrian bridges over the Caltrain tracks at 22nd Street, 23rd Street, and Paul Avenue in San Francisco. Existing abutments will also be retrofitted to support the new structure. Utilities supported by the bridges will be temporarily relocated during bridge removal and construction.

The three bridges are deemed structurally deficient, do not meet existing seismic safety standards and must be replaced to ensure the safety and well-being of community members and Caltrain passengers.

Construction Impacts

Work to replace the bridges is scheduled to start in early 2015 and is expected to last 9 to 12 months per bridge. While a majority of the work will be completed during the day, in order to maintain rail operations, night and weekend work will be required for some construction activities. 

Community members may experience temporary, localized noise impacts during construction. Construction crews will use best management practices to reduce noise and other impacts to the community and Caltrain will notify community members well in advance about construction activities that could result in noise impacts. 

Construction Sequence

To limit impact on traffic, construction of the 22nd and 23rd street bridges will not take place concurrently. Construction will begin with the 23rd Street Bridge, followed by the 22nd Street Bridge. The construction sequence for the Paul Avenue Bridge is not impacted by the other bridges. 

Project Schedule

  • 23rd Street: Late April 2015 to March 2016 (Completed)
  • Paul Avenue: Jun. 2015 to Nov. 2016 (Completed)
  • 22nd Street: April 2016 to May 2017

Public Outreach & Community Engagement
Caltrain will be engaging the public in multiple venues to provide more information and collect feedback about the project. Nearby residents and business will be notified via mail about upcoming community meetings. Caltrain will also be working with local community-based organizations to build awareness about the project and its impacts.
