Community Meeting on the 25th Avenue Grade Separation Project on April 11

Caltrain will be holding a community meeting regarding the 25th Avenue Grade Separation Project on Tuesday, April 11, from 6:30 p.m. to 7:30 p.m. inside the First Presbyterian Church’s Lighthouse Room at 194 W. 25th Ave in San Mateo.

Construction on the $180 million 25th Avenue Grade Separation Project is scheduled for fall 2017 and is expected to span two and a half years.

Caltrain, in cooperation with the City of San Mateo, will raise the tracks and slightly lower the road (grade separate) at 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 provide an opportunity to complete east-west street connections at 28th and 31st Avenues.

As part of the project improvements, Caltrain will build a new elevated Hillsdale Station at 28th Avenue. The new station will offer updated amenities and will allow for better safety and reduced traffic. 

In September 2018, Hillsdale Station will be closed for up to five months to allow for the building of a new elevated Hillsdale Station. Additional Caltrain service will be provided at the Belmont Station, as well as a SamTrans bus bridge along El Camino Real between Belmont and Hillsdale.

Additionally, the work requires the closing of E. 25th Avenue for approximately two months, with construction on the street occurring from Spring/Summer 2019. All businesses on E. 25th Avenue will remain open during this time.

The meeting will include a presentation detailing the project scope and tentative construction schedule. For more information on the project, please visit
