25th Avenue Grade Separation Project

Night Work
None.

Weekday Work 
(Monday, December 13 to Friday, December 17)
  • Borel: Crews will grade and install planting and irrigation.
  • Hillsdale: Crews will conduct grading

Background
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 between E. 28th and E. 31st Avenues. 

In order to maintain regular train service, some activities will be conducted during nights and weekends, outside of normal train service hours. Neighbors may experience construction noise and light during these times. The overall project construction is expected to be complete in fall 2021.

Caltrain Electrification
Caltrain Electrification is a key component of the Caltrain Modernization program which will electrify the Caltrain Corridor from San Francisco's 4th and King Caltrain Station to approximately the Tamien Caltrain Station.

The primary purpose of Caltrain Electrification is to improve Caltrain system performance, reduce long-term environmental impact by reducing noise, improving regional air quality and reducing greenhouse gas emissions. An electrified Caltrain system would better address Peninsula commuters' vision of increased service and improved travel times in an environmentally friendly and reliable way. This also is expected to help accommodate increase system ridership through improved system operations.
