SF Weekend Caltrain Service Closure

Weekend SF Caltrain Closure


As part of the Marin & Napoleon Rail Bridge Improvement Project, the Napoleon Street Bridge will be replaced and require two weekend service closures*:

  • Saturday, April 17 and Sunday, April 18, 2021
  • Saturday, April 24 and Sunday, April 25, 2021

On these weekends, free SamTrans bus service will replace train service between Bayshore, 22nd Street and San Francisco stations. SamTrans will provide enough buses for social distancing and face coverings are required. Buses are ADA accessible and will have limited capacity for luggage and bikes onboard.

We thank you for your continued patience.

*Subject to change according to construction work.

Project Background

The Marin and Napoleon street bridges are located near the base of Islais Creek, under the I-280 freeway, in San Francisco’s Bayview neighborhood. The Napoleon Street Bridge will need to be fully replaced for safety and structural integrity purposes, whereas minor safety improvements will be made to the Marin Street Bridge. Additional track work may occur from Cesar Chavez to Jerrold Street.

Station Impacts

There will be Caltrain staff at the San Francisco and Bayshore stations to assist riders.

San Francisco

The San Francisco Station lobby will remain open for access to ticket machines and Clipper Add Value machines. Bathrooms are closed due to COVID-19 regulations.

22nd Street

22nd Street Station will be CLOSED with no access to Clipper Add Value or ticket machines. Riders that normally use 22nd Street can use the free bus service and purchase tickets at Bayshore Station.


Bayshore Station will be open. There will be no weekend parking in the Bayshore station parking lot. There will be limited parking on the street.

Ways to Pay

Clipper customers traveling south from San Francisco or 22nd Street stations can tag on at Bayshore Station and tag off at their final destination.

Ticket Machines

Transit Alternatives

In addition to the free SamTrans bus service provided, please see our transit alternatives page for other transit options that may work better for some passengers.

April 24-25: 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.
