BART starts one hour later for massive seismic retrofit of Transbay Tube

FILE ART - BART

Beginning on Monday, BART service will start an hour later for a massive project that will seismically retrofit the Transbay Tube over the next five years.

Instead of giving the roughly 2,900 riders a ride at 4 a.m., the trains will start running at 5 a.m., BART said.

To help those commuters out, BART is launching a bus service, called the Early Bird Express. There will be 14 new bus lines running between 3:50 a.m. and 5:30 a.m.

The retrofit and service change will last until at least 2023. Last year, BART awarded a $313-million contract to Shimmick Construction and California Engineering Contractors Inc. to shore up the outer shell and concrete liner of the Transbay Tube.

Details on the new hours and bus service are here.
