Caltrain grade separation

  • Project typeTraffic and transportation

This project is evaluating the engineering feasibility of replacing the existing at-grade crossings of the Caltrain tracks by building grade separations of the roadways from the tracks at Ravenswood Avenue, Oak Grove Avenue, Glenwood Avenue and Encinal Avenue, with priority on Ravenswood Avenue.

This project was funded in part by a grant from the San Mateo County Transportation Authority Measure A Grade Separation Program.

Current status

This project evaluated two alternatives as directed by City Council:

  1. An underpass at Ravenswood Avenue only, leaving the remaining crossings at-grade as existing
  2. A hybrid option (partially raised rail, partially lowered roadway) that would grade separate Ravenswood, Oak Grove and Glenwood avenues, leaving Encinal Avenue at-grade as existing

On March 5, 2019, City Council approved the final project study report(PDF, 6MB) with the hybrid option (Alternative C) grade separating Ravenswood, Oak Grove and Glenwood Avenues as the preferred alternative. Encinal Avenue would remain open and at-grade under this alternative.

In October 2019, staff submitted an application in response to the California Public Utilities Commission's Section 190 request for projects to prioritize this project location. Staff submitted an application to renew the City’s status on the Section 190 list and the project is currently ranked fourth in the state.

Additional studies

Due to community feedback received when selecting the City's preferred alternative, City Council directed staff and the project team to develop a scope of work to further evaluate a fully elevated alternative. That draft scope of work was approved in January 2020, but subsequently put on hold due to the COVID-19 pandemic.

On October 18, 2022, the City Council approved a revised scope of work and directed staff to coordinated with members of the public on potential additional studies of impacts of a fully elevated alternative.
