Don't you know Karl Rove has a time machine? He keeps it right next to the weather-controller. Yeah, he and the Pres went back in time 40 years, messed with the design for this bridge and returned undetected.
Or so they thought......

Of course there?s a design flaw. While we don?t know what initiated the collapse, we do know that because of the design, the whole bridge came down. A proper design wouldn?t have the whole thing coming down when just one section has failed. Sorry, but it's not "of course" there is a design flaw. In fact the more likely culprit will be about maintenance than design. This bridge stood for 40 years under far greater loads than were present when it fell. That doesn't imply a design weakness at all.
With regard to a single failure bringing down the whole bridge this is almost to be assumed with such structures. Bridges stand because they divide, spread and balance enormous forces. A break anywhere in the structure will almost always bring the entire thing down.
It could turn out to be any number of things. Most likely a combination of things. But the place to look first will be all about metallurgy and maintenance.

It did; the code changed the next year (1968).

Sorry, but it's not "of course" there is a design flaw.I didn't say a design flaw brought it down. I have no idea what did initiate the collapse and even said so. I implied it was a poor design for the whole thing to come down because of a failure in one section. This isn't a suspension bridge. The adjacent bridge has a much better design. The Oakland bay bridge suffered heavy damage in the '89 quake and one section failed and dumped cars into the bay, but the whole bridge did not collapse due to the failure of the one section.

Oh this is such BS.
Did you not see the before pics and reports that indicate the DOT was storing road base and construction material ON THE BRIDGE prior to collapse?
The bridge was IN USE, under construction?????

Think of a stone arch. Pull one stone and the whole arch fails.
In a truss bridge a failure of any segment likewise will compromise the entire structure.
The sections that fell in the bay bridge were just that. Sections of roadbed that broke. There is no parallel to this bridge.

Nine popped/broken and missing rivets. No tears in the holes on the gussett or framing. Rust/corrosion is my guess.

I didnt know Bush was designing bridges 40 years ago.No, fully certified mechanical engineers did this and apparently they don't know what Shinola is.

The real miracle here is how this "flawed" bridge managed to elude the sharp eyes of the Clinton administration for 8 years without Clinton and his band of sharp-eyed bridge checkers dicovering its flaws. Wow!
Extreme sarcasm/off

What is strange about this is that traffic had been reduced in both directions if reports I heard are true. One would think the load was probably 1/2 what it normally was. Why would it fail now if these plates were the issue? Due to Bush's terrible economy and Bush's high gas prices, only 1/2 of the normal traffic was necessary for the bridge to fail, because Bush's Global Warming had already weakened the plates, and they failed, even before Al Queda could blow them up because Bush didn't catch them due to Bush's quagmire in Iraq.

Were our bridge designs outsourced to Mexico 40 years ago?

Hey, Tom, that's not bad!
Just with an offhand post, you make more sense than the moonbats (granted, that's like shooting a tuna fish in barrel, but even so...).
