For now, at least, Fremont Street is closed, First Street is semi-closed, the terminal is closed, and the investigations are underway.

First Street between Howard and Mission streets will close at 9 p.m. over the next few days as crews work to reinforce the bus deck above. The stretch of street will reopen at 5 a.m. on each of the following days.
No cracks were found in steel beams above First Street but two cracks were found in steel beams on the bus deck above Fremont Street on Sept. 25, prompting the immediate closure of the transit center and Fremont Street.
Mark Zabaneh, executive director of the Transbay Joint Powers Authority said in a statement, “Because Fremont and First streets are similarly designed, to be prudent, we have decided to reinforce First Street as a proactive measure.
Some of the damaged material has to be removed, in order to figure out the details of the damage, before a repair plan can even be formed: Plans revealed for testing cracks in steel beams at Salesforce Transit Center in San Francisco
The beams have been in place since January of 2016, fire proofing material was installed in June of 2016. TJPA says they know the cracks happened sometime after that, they just don't know when.
"As dire as the situation is it's a blessing that we're able to catch it," said Zabaneh.
During a presentation Tuesday to the TJPA board officials outlined the calendar to get the building re-opened.
Jacks will be replaced by a temporary shoring system to relieve the stress on the cracked beams. Once that's in place, Fremont Street will be re-opened; the goal by next Friday.
"At that point in time we'll be able to take a sample of the steel girder, take it to a lab and do various tests," said Zabaneh.
Those tests which will take approximately two weeks will help determine what caused the cracks. A critical piece of information not just for curiosity's sake but because the cause will dictate the fix. There will be peer reviews both before and after the permanent fix is installed.
People of course continue to argue about that most human of complaints: who pays? ne of few certainties with Transbay center: Repair costs covered by warranty
The cost of repairing the Transbay Transit Center, a task that is likely to take weeks and cost millions, will be covered by warranty, officials confirmed Wednesday.
The general contractor or its subcontractors are responsible for repairing any construction flaws, not the center’s operator, the Transbay Joint Powers Authority.
In the meantime?
And, as they say, life goes on.
