CONSTRUCTION
South San Francisco Station Improvement Project
Night/Weekend Work
At night on Friday, April 9 to Sunday, April 11, construction crews may be working on the pedestrian underpass tunnel and installing the new signal cantilever. Neighbors should expect some noise. Night construction hours will be from 6 p.m. to 5 a.m.
Weekday Work
During the day on Monday, April 12 to Friday, April 16, construction crews may be shoring near the west plaza area and the East Tunnel near Poletti Way. Shoring work consists of metal sheets being installed in the ground to create a retaining wall. This may require the use of excavators and other heavy machinery. Construction crews may be working extended hours from 6 a.m. to 6 p.m. One lane of Poletti will be closed and traffic control will be along the road during construction.
Neighbors may hear additional noises from heavy machinery and equipment backup alarms. We apologize for any inconvenience these activities may occur.
Traffic Notices
Poletti Way Traffic Notice
Due to construction, Poletti has been converted to a one-lane street. Traffic control is in place to guide traffic. Poletti will remain a one-lane road for the duration of the project. There will be no impacts to the 101 off-ramp.
After the completion of the South San Francisco Station Project, Poletti Way will become a two-way street, with the Southbound lane being reserved for buses serving passengers at the new South San Francisco Station.
25th Avenue Grade Separation Project
Weekend Work
On Saturday, April 10, at 31st Avenue crews will install a waterline and street lighting and will strip the retaining wall forms. At 25th Avenue, crews will remove surface features, excavate and grade.
Weekday Work
(Monday, April 12 to Friday, April 16)
- 28th Avenue: Crews will paint and install fencing, landscaping and irrigation.
- 31st Avenue: Crews will excavate and install a water line and street lighting, and will form, pour, and strip the retaining walls.
-
25th Avenue: The street and sidewalk will be closed between S. Delaware and Palm Avenue so crews can lower the road (more information). Crews will also remove surface features, excavate, grade, and will form, pour, and strip the retaining walls.
- Permanent Parking Lot: Crews will install landscaping and irrigation.
-
10th to 14th Avenues: Soil was originally distributed in this location in preparation for a replacement parking track as the previous one was removed due to the grade separation project. To view the latest updates and for more information visit www.Caltrain.com/SMParkingTrack.
Hillsdale Station Closure
This past spring, the Caltrain Hillsdale Station temporarily closed to allow for construction of the new track alignment, the lowering of 28th Avenue, and the building of the new station. Due to COVID-19 and the pandemic's impact on the project supply chain, the new station is now anticipated to open spring 2021, dependent on labor and materials. To watch the archived virtual town hall from April 2020, click here.
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. Please note the Hillsdale Station temporarily closed in spring 2020, for the building of the new elevated Hillsdale Station. To learn more, please visit www.Caltrain.com/HillsdaleTempClosure. We apologize for any inconvenience this may cause. 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.
For information on upcoming community construction update meetings, please visit the Caltrain Electrification Project events page at www.CalMod.org/Events.
