BART later tweeted that the major delay from the Civic Center closure was forcing the transit agency to diver select East Bay trains in order to “continue service and reduce current bottleneck headed into San Francisco.”

Riders were advised to watch platform signs and listen to operator instructions.

At around 6:20 p.m., BART officials said that the scene had been cleared and the station had reopened.
