Every bridge in the SF Bay Area could be damaged severely in one major earthquake on the Hayward Fault, except for the Golden Gate Bridge. It might be spared if a major earthquake in magnitude and duration strikes on the Hayward Fault. This is because the energy would be spread out into all the associated fault that splinter off from it. The Hayward and San Andreas Faults are separated by a large sandy area that makes up the bay waterways. The tectonic pressure forces pass under and then create the Diablo Range that connects to the San Andreas south of the bay.
Many of the associated faults are named differently, but they are all connected. Therefore, if the Hayward Fault experiences a massive movement, all the associated areas will as well. If the Hayward Fault moves on the western side, the Golden Gate could be affected. If the movement is mostly on the eastern side, then bridges and levees would be affected severely, leaving highways and byways impassible.
This means emergency service would be inhibited. Helicopters would have to be used to evacuated injured. Commuters would be stranded everywhere. Commerce throughout the state and on the entire west coast would be halted. Communication lines would be damaged. Water supply lines would be ruptured, along with gas pipes. Power lines would be down. Fires would rage everywhere, with no water pressure to fight them with. Levees would most likely fail, flooding even the state capital under many feet of water.
Any large earthquake on the Hayward Fault would possibly lead to large movements on other faults in the Bay Area, too, including anyplace along the entire length of the San Andreas Fault and The Cascadia Subduction Zone.
See here how the faults are all associated like the wrinkles that form if you push on your own skin:
We as Californians, along with everyone in this nation and the world, are someday in for a wild ride of survival. State Government Leaders should take heed of this warning and prepare appropriately with plans to mobilize fire-boats, helicopters from civilian and military positions, along with preparing all citizens to be as independent as possible in the event of this future event. That way, more people may survive, and the emergency services will face the least amount of strain on their resources and personnel.
Everyone, everywhere on this planet that is able, should have anwith them at all times, for their own personal benefit.
