Civic Center BART station reopened half an hour after it closed Wednesday afternoon due to flooding, the agency said.

Both the platform and concourse levels were flooded, said Anna Duckworth, a BART spokeswoman. The agency closed the station at 2:49 p.m. and barred riders from entering while Muni engineers and BART police worked on the problem.

🙏🙏 Civic Center Station is now RE-OPENED. Trains are stopping at the station now, according to our Operations Control Center. Thanks to all for your patience and sorry for the inconvenience. — SFBART (@SFBART) January 16, 2019

According to the agency, a problem on the Muni platform was causing water to leak onto the BART platform below. Trains did not stop at Civic Center BART during the closure.

The station reopened at 3:23 p.m.

The U.N. Plaza entrance is still closed, according to BART, to get standing water off street level.

Muni remained open during the closure, said San Francisco Municipal Transit Authority spokesman Paul Rose.
