SAN FRANCISCO (CBS SF) – Homes and businesses in part of San Francisco’s Mission District were evacuated Wednesday morning because of a gas leak, authorities said.

The leak was reported at 10:39 a.m. near 24th and Bryant streets by an off-duty firefighter, fire spokeswoman Mindy Talmadge said.

Buildings within a one-block radius of the leak were evacuated just before 11 a.m., fire officials said.

PG&E spokesman Joe Molica said a contractor struck and ruptured a 2-inch plastic line in the middle of the intersection, at a spot where many lines connect.

The leak was capped around 12:30 p.m., nearly 90 minutes after initially reported.

The area was briefly shut down to traffic, Talmadge said. San Francisco Municipal Railway’s 48-Quintara bus line was rerouted because of the incident, Muni spokesman Paul Rose said.
