A major impact on your morning commute! 

The brand new Transbay Transit Center in San Francisco shut down after a crack was found in a beam in one of the buildings. 

This comes as the annual Salesforce “Dreamforce” conference is happening just a few blocks away. 

Howard Street between Third and Fourth Streets will be closed all week because of the conference. 

This is going to cause a major traffic headache this morning. 

People are being advised not to drive in downtown San Francisco if they can avoid it. 

This is also going to affect Muni and AC transit lines.

The mayor of San Francisco says the city’s new $2 billion transit terminal where a crack was found in a support beam will stay closed until officials determine it’s safe to reopen it.
    
Mayor London Breed said she visited the Salesforce Transit Center on Wednesday to meet with officials assessing the crack found Tuesday by workers installing roofing tiles.
    
Breed says a thorough investigation will be conducted to determine what caused the crack, who is responsible and when the transportation hub can safely reopen. She didn’t say when that would be.
    
Officials closed the center during Tuesday afternoon rush hour. Buses are being rerouted to a temporary transit center about two blocks away.
    
The five-level center that opened last month includes a bus deck, a central entrance hall and a rooftop park with an outdoor amphitheater.
