4:31 PM: A gas main break that caused part of San Francisco’s South of Market neighborhood to be evacuated this afternoon has been capped, officials said.

The rupture was first reported at around 12:10 p.m. near Fourth and Market Streets, where a construction crew reportedly struck a six-inch gas main, PG&E spokesman J.D. Guidi said.

Several buildings and businesses in the area were evacuated, including Moscone Center and Yerba Buena Gardens, San Francisco police Officer Albie Esparza said.

Several residents were shuttled on Muni buses to a nearby church, a fire department dispatcher said.

The leak was capped around 2:48 p.m., Guidi said.

PG&E is still working to repair the pipe but people are being allowed to return to their homes and businesses in the area, according to city officials.

No injuries have been reported.

Traffic has reportedly been very heavy in the area.
