Grade Crossing Improvement Before and After 2nd St San Mateo
2nd Street, San Mateo before and after the crossing improvements.

Caltrain, with our city partners, has worked to improve the safety at 5 at-grade crossings (intersections where train tracks cross a street) in San Mateo and Menlo Park. These improvements will increase the safety for vehicles, pedestrians and cyclists.

Project Details

Improvements include more clearly-marked pedestrian crossings with new paint striping and lettering, pavement markers, and the installation of a fixed median with flexible bollards. The median is designed to prevent motorists from driving around lowered crossing gates.

In limited locations, installation of the median and flexible bollards will permanently alter driveway access. See illustrative graphic above depicting general elements of planned improvements. 

Grade crossing improvement sites include:

  • 1st Ave. and S. Railroad Ave., San Mateo
  • 2nd Ave. and S. Railroad Ave., San Mateo
  • 3rd Ave. and S. Railroad Ave., San Mateo
  • Glenwood Ave. and Garwood Way, Menlo Park
  • Oak Grove Ave. and Merrill St, Menlo Park


All active construction planned for this project in Menlo Park and San Mateo has been completed. We've appreciated the community's patience and cooperation as we've worked to improve the safety of these crossings.  


State Funding: $1.4M

Completed Crossings - 2018
