Caltrain: 25th Avenue Grade Separation Project

Project Description:

Caltrain, in cooperation with the City of San Mateo, will raise the tracks and slightly lower the road (grade separate) at E. 25th Avenue in San Mateo. 

This will improve safety for both motorists and pedestrians, and it will reduce local traffic congestion in San Mateo. 

In addition, the project will create new east-west street connections at 28th and 31st Avenues; and as part of the project improvements, Caltrain will build a new elevated Hillsdale Station with updated amenities at E. 28th Avenue. 

The track raise in turn provides the opportunity to complete east-west street connections at 28th and 31st Avenues in conformance with the San Mateo Rail Corridor Transit Oriented Development Plan.

The Hillsdale Caltrain Station will also be relocated northward between 28th and 31st Avenues as part of the improvements.
