San Francisco’s new Transbay Transit Center will remain closed at least through the end of next week, officials said Wednesday, after yet another cracked beam was discovered during an overnight safety inspection.
The $2.2 billion hub for buses and eventually trains, which opened just last month as the flashy centerpiece of city infrastructure, was closed abruptly Tuesday afternoon after a fissure was spotted in a beam that helps hold up the sprawling complex.
The initial tear runs about 2½ feet long and 4 inches deep through the bottom of a 60-foot-long beam that supports both the center’s celebrated rooftop park above and a bus deck below, officials said. The beam is located over Fremont Street, between Mission and Howard streets. The second crack is in a parallel steel beam that also crosses Fremont Street. It was described as slightly smaller.
Representatives of the Transbay Joint Powers Authority, which built and operates the transit center, said Wednesday they didn’t know the causes of the cracks, but they remained concerned about the potential for the beams to fail. Fremont Street, which passes under the center, also is scheduled to stay closed through Oct. 5.
“We will not open the transit center or Fremont Street until we are certain the issue is 100 percent rectified,” said Mark Zabaneh, executive director of the TJPA.
