BART – Transbay Tube Retrofit will shift start of service to 5am starting February 11, 2019

The Transbay Tube is BART’s most critical asset. Although the tube is structurally sound, in a very large and very rare earthquake event, the outer shell and concrete liner are predicted to crack, causing leakage.

To address concerns of flooding in the event of a 1,000 year earthquake, BART has awarded a 313-million dollar contract (to Shimmick Construction and California Engineering Contractors Inc.) for a massive project that will retrofit the Transbay Tube.

To give crews the time needed to get the work done, BART plans to open the entire system one hour later on weekdays for the project’s duration. This means changing from a 4:00 a.m. to a 5:00 a.m. start of service for a period of up to 3.5 years. The 5 am opening is temporary. There have been no discussions nor actions taken to make it permanent. A careful evaluation of both our riders needs and maintenance requirements would be conducted before any such decision would be made.

This extra hour each night will extend the available work window by at least 20% and save the project a minimum of $15 million.

Adding this one hour will shorten the project timeline by 4 months.

The specific date for when the service change will take effect is February 11, 2019.

A finalized alternative bus service plan complete with parking payment options was presented to the Board on October 11, 2018. Preview the board presentation.

Once the schedule change takes effect, end of the line trains will begin around 5 am, Trains will also for the first time begin around 5 am from midline stations (Concord, South Hayward and Daly City) to ramp up the start of service more quickly. All of the trains will start service long with the first train arriving at Embarcadero Station at 5:30 am.
