The 25th Avenue Grade Separation project for Caltrain will raise the tracks and 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 to separating the tracks and road at E. 25th Avenue, the project will provide an opportunity to complete east-west street connections at 28th and 31st Avenues. A new elevated Hillsdale Station located at E. 28th Avenue will also be constructed. The new station will offer updated amenities and will allow for better safety and reduced traffic.
