Beginning February 11, 2019, BART will shift its start of service from 4am to 5am on weekdays to allow extra time for a critical seismic retrofit of the Transbay Tube. This change will last for the duration of the 3.5 year-long project.
About 2,900 riders enter our system in that first hour of service.
A robust alternative bus service plan called the Early Bird Express has been developed for the 4 am hour.
The Early Bird Express alternative bus service plan establishes 15 new bus lines to run between 3:50 am and 5:30 am in both directions between stops. There will be 7 transbay routes, 5 East Bay routes, 2 San Francisco/Peninsula routes and a Contra Costa County route. The bus network will serve 21 BART stations and the Temporary Transit Center in San Francisco.
