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, June 19, at 31st Avenue and in the parking lot, crews will install subgrade and pave.
Weekday Work
(Monday, June 21 to Friday, June 25)
- 31st Avenue: Crews will paint the bridge, subgrade, pave, make concrete improvements and relocate a traffic signal.
- 28th Avenue: Crews will install drainage.
-
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 relocate street lighting and a traffic signal, grade, and make pavement improvements.
- Borel: Crews will grade for the retaining wall and pour foundations.
- Permanent Parking Lot: Crews will install landscaping and irrigation, subgrade and pave.
-
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.
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.
How to Stay Informed
For more information on the 25th Avenue Grade Separation Project, please visit www.Caltrain.com/25thgs. For questions about the project, please call the Caltrain Customer Service at 1.800.660.4287 or email SMgradesep@Caltrain.com.
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.

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. No parking track installation will occur, as a construction contract has not yet been issued. A survey regarding neighborhood enhancements for the parking track was conducted and the results are now posted online. For more information visit, www.Caltrain.com/SMParkingTrack.
Caltrain Grade Crossing Improvements Project in San Mateo and Menlo Park
Caltrain, in cooperation with our city partners, are working to improve the safety at 5 at-grade crossings (intersections where train tracks cross a street) in San Mateo and Menlo Park. These improvements will increase the safety for vehicles, pedestrians and cyclists. Improvements include more clearly-marked pedestrian crossings with new paint striping and lettering, and pavement markers. The improvements also include the installation of a fixed median with flexible bollards. The median is designed to prevent motorists from driving around lowered crossing gates.
While the majority of active construction work planned in Menlo Park and San Mateo has been completed, you may notice that crews continue to be on-site to complete minor painting and re-striping work over the next few weeks. Work hours will be Monday through Friday from 7:00 a.m. to 5:00 p.m. In addition, in response to feedback from the community, we will be making modifications to the median at Glenwood Avenue and Garwood Way in Menlo Park. These modifications (which include the installation of additional reflectors and enhanced painting) are designed to increase the visibility of the median. We appreciate the community’s patience and cooperation as we’ve worked to improve the safety of these grade crossings. For more information, visit www.Caltrain.com/GCImprovements.

Atherton Station Platform Removal
Starting Monday, May 10, Caltrain crews will begin removing the centerboard platform and pedestrian crossings at the Atherton Station. In November 2020, the Town of Atherton endorsed the closure of Atherton station subject to an Agreement on a Memorandum of Understanding (MOU) between the two parties. In December 2020, Caltrain approved the permanent closure of the Atherton Station.
The demo work will be completed during the day and will require the use of a jackhammer, excavator and other equipment to remove the concrete platform. Residents can expect to hear construction noise as this work is completed. We apologize for any inconvenience this may cause. The platform demo work is expected to take one week to complete. Crews will return at a later date to place additional ballast along the tracks.
This work will also require intermittent, temporary traffic control on Fair Oaks Lane. Flaggers will be present at each side of the railroad crossing to temporarily stop traffic and direct work trucks to enter/exit the platform work area as needed.
