Caltrain's Marin and Napoleon Street Rail Bridge Improvements project, is needed to protect the safety of both riders and the community. The project will require two weekend service closures beginning Saturday, April 17. The construction is scheduled to take place the following weekends:
Saturday, April 17 and Sunday, April 19- Saturday, April 24 and Sunday, April 25
Free bus service will replace train service between Bayshore and San Francisco stations during all San Francisco service closures. Buses are ADA accessible and will have limited capacity for luggage and bikes onboard. We thank you for your continued patience. For more information visit Caltrain.com/SFWeekendClosure.
Caltrain strongly recommends riders traveling to watch the San Francisco Giants or the Golden State Warriors on the weekend of April 24-25 to use BART at Millbrae station or an alternative transit option, due to limited capacity on buses and social distancing requirements that will make it difficult to accommodate the influx of riders.

CONSTRUCTION
South San Francisco Station Improvement Project
Night/Weekend Work
On Saturday, April 24, construction crews may be working on the pedestrian underpass tunnel on the east side of the station near Poletti Way.
Weekday Work
During the day on Monday, April 26 to Friday, April 30, construction crews may be shoring near 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.

Hillsdale Station Opening - April 26, 2021
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.

Caltrain Grade Crossing Improvements Project in San Mateo and Menlo Park
Caltrain, in cooperation with our city partners, will begin a project 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.
During the week of April 23th, crews will continue work at the intersections of 1st, 2nd and 3rd Aves. and S. Railroad Ave. (in the city of San Mateo) to install fixed medians, including the flexible bollards. The median will help prevent motorists from driving around lowered crossing gates. Work hours at and around each crossing will be Monday through Friday from 7:00 a.m. to 5:00 p.m. Construction-related noise (e.g. backup alarms, hammering, etc.) should be anticipated during these hours. In addition, it may be necessary to temporarily re-route traffic (vehicle and bicycle) around lane closures at each crossing. Flaggers will be in-place to help re-route traffic safely. We do not anticipate any parking impacts. For more information, visit www.Caltrain.com/GCImprovements.
