EAST-WEST CONNECTION OPENS AT 28TH AVENUE

Video of the 28th Avenue connection being constructed from start to completion.

On March 1, 2021, the new connection at 28th Avenue opened. This is a major project milestone, as pedestrians, cyclists, and motorists can now seamlessly travel between east and west, separated from the train tracks. Watch the transformation of 28th Avenue from start of construction to the road opening in this short video.

Drivers are encouraged to use 28th Avenue while E. 25th Avenue is partially closed so it can be lowered as part of the grade separation project. More information here.

Project Background

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