BART will start service one hour later beginning next month, a change that will  last for 3.5 years as work is done to gird the Transbay Tube against a massive earthquake.

Beginning Feb. 11, BART will start service at 5 a.m. instead of 4 a.m. Buses will be used to cover that first hour, in which 2,900 passengers use BART.

BART will also be single-tracking trains through the tube Sunday through Thursday from 9:30 p.m. until close of service at midnight. During this time, trains will run every 24 minutes instead of the every 20 minutes.

While the tube is structurally sound, in a very large and likely rare earthquake, the outer shell and concrete liner are predicted to crack, causing leakage.

Before traveling, BART urges rider to check its website and app before traveling.
