Expect early-AM weekend Transbay Tube delays through January

As part of our continuing Earthquake Safety Program, we are adding critical emergency power supply improvements between Embarcadero and West Oakland stations. To complete this work we will continue closing one track in the Transbay Tube on Saturday and Sunday mornings in November, December and January. The work required takes more time than our regular overnight maintenance window allows and is taking longer than originally expected. We have chosen this time in an effort to cause the least inconvenience to our customers. We apologize for the delay.

The morning work will continue to occur during the first two hours of service on Saturdays and Sundays. Service through the Transbay Tube during those hours may experience a 10-15 minute delay between Embarcadero and West Oakland stations. We will do everything possible to keep the delays to a minimum.

We appreciate your patience as we perform this necessary work to build a better BART. Please visit www.bart.gov for additional information.

Updated Dec. 17 to reflect work continuing through January.
