The Bay Bridge did not collapse, I was there that night, only one piece fell from the upper deck, like a trap door.
Only the Cypress Freeway fell down, and only the top section of that. I remember driving back in the dark and detouring around it as all the emergency vehicles and personal were racing around the scene. There were chunks of concrete everywhere on my ride home from Oakland, after driving south to the Dumbarton to get across from San Francisco to Oakland after leaving the World Series that night, I ended up getting home at some very early in the morning hour.

I have tried to get a real close up picture of the break in the link on the SF-Oakland Bay Bridge. I feel sure there are some, somewhere, but I don't expect to see any from the Bridge Engineers. Any Pictures I would want to see would probably come from a Private Photographer, or a Commercial Photog. My guess is there are a lot of Camcorder shots, with very good resolution, that could be shown, or a Photo Capture of the break. I expect nothing from the Ca. People. Their Spokesman tried to minimize the Problem right from the start of TV coverage. He stated there was a crack, and some rust. Whoo-ee! I wonder if there are other Links of this type that have frozen solid from Rust. Just askin'. How safe is the New Eastern Section of the Bridge? It isn't even built yet and "They" are finding numerous defective welds in the sections coming from China, and is it true that Chinese welders are getting bonuses to speed up the work? There are many questions about payoffs to welders, also Inspections,etc. There will be a lot more questions about the design and construction of this section of the bridge. Oh yes, there will be another section of the bridge built, to finish the bridge to San Francisco.

I thought the skyway portion was built in Stockton, but I don't know where the SAS part is being built. In any event, me sources in China could not confirm any shenanigans.

but the thought does cross my mind everytime, though.

I get a feeling that the design engineers of the new Eastern Bridge were more interested in Form, over Function.

Capt:Thanks for your Photo. I have this one, and it's clarity is the same. I'm sure there are clear close-up Pictures of that break, but I don't expect to get any. I did get a better look at the break on one of the News Programs, but I didn't record it. The engineers would have good Pics, but they won't show them to the American Public. Maybr later on in time they will slip out so we can see the break and the fittings.
Crossride: I caught this info from a News Clip that came and went, on TV, so fast that I almost missed it. There will be lots of people watching for the outcome of what is happening with that part of the bridge. There was an "Animated Film" of what would happen to the new section of the bridge, on TV, if there was a strong quake. That was like Spaghetti whipping all over the place. It made even me wonder about that structure.
I think the "People" should be given more information as to what is going on with that bridge. It isn't impossible for Engineers to make fatal design flaws in structures. A most notable case is the Tacoma, Washington Bridge, which was about one year old, and about the same as the Golden Gate Bridge, except that the Tacoma bridge had only one roadway on the bridge. That was it's flaw. The wind whipped that bridge all over the place until it broke apart and fell down. The Tacoma Bridge had no "Stiffening Members" below the roadway to dampen any wind factor that caused the failure of the Bridge.
I see other structures that I feel are unsafe to drive on as a relatively small quake could bring them down.

Just a note: Concrete is not "Forever". The probable useful life of structural concrete is about 35 to 40 years. The safe, useful life of concrete can be stretched out to many more years, but there are no guarantees where safety is concerned.

My guess is that there will be no "sure fix" for the damaged Eye Bar. Until I hear the Real reason for the break, then all is just an experiment. There was a great strain on the "Eye" and I have heard no explanation yet as to why it broke. Metal Fatigue will not do as an answer. Neither on the first break,nor on the second break, of the repair. I would be somewhat happier if the people in charge would just tell the public to make arrangements for long term detours and then tell them that the bridge will be closed until further notice. This event will not be quieted down by a few people trying to minimize the seriousness of it all by a "Hard Hat" glossing over the truth, on TV. That's the way I see it.

There are good closeup photo's of the break and repair on SF Gate.

Yes heckheckle, a good call. They were lucky no one was seriously hurt or died.
