The agencies have all met. They all have back-up plans ready to go. Commuters, on the other hand, are not quite as prepared.
BART officials say they are going to use every single car they have Tuesday morning if the bridge does not reopen. No cars will sit idle for maintenance or rest. They will however, shut down the 24-hour service that ran over the weekend. They have to do some required maintenance, so the trains will not run from midnight Tuesday to 4 a.m. Tuesday.
BART officials think they will be able to handle the extra passengers. They have planned for this for months. It is the commuters who were a bit flat-footed Sunday. Some did not plan for a possible closure through Tuesday.
"I'm not going to work on Tuesday, so it won't be a problem for me. But, if I do I'll just go back… oh, I won't be able to take it back. I'll take the Golden Gate Bridge and just go around," one woman told ABC7.
The Golden Gate Bridge was jammed over the weekend. Officials fear Tuesday would be worse. Southbound 101 into the City from Marin County was stop-and-go. They will open four lanes into the City on Tuesday if the Bay Bridge is still closed. There is not much else they can do.
They will also add a Larkspur Ferry at 7:30 in the morning. The Alameda Harbor Ferry will double its service as they did last Friday. The Alameda-Oakland Ferry will triple its service Tuesday if the Bay Bridge is still closed.
BART is very concerned about its parking lots because they cannot add any spaces. Customers may want to reserve a space, something that can be done at BART's website. Commuters might also consider carpooling or getting dropped off.
