I work for a company that engineers bridges, including significant work in the area. The people here who are smarter and more educated than me agree with Brian Maroney.
People smarter and more educated than me thought the Vietnam war was a great idea, and Iraq even better. :laughing
I have no idea whether the bridge is safe or not. I suspect the chances are around 95% that it is. However, given the way the state has behaved and the INCREASING number of problems showing up, I have zero confidence in Caltrans, the state, and their pronouncements. NOBODY is going to risk their job by going against the state's version of what has happened and will happen.
That's why I said 'imagine". If in fact, the bridge turns out to be an utter debacle, which is possible but unlikely, it will turn Sacramento upside down and change the political structure of CA, not to mention destroy the economy of the Bay Area.
If Caltrans even published ANYTHING that even inferred there might be a problem, the impact would be disastrous. So count on them lying in any event. There's nothing else they can do.
Remember, there's almost certainly nothing wrong with the DESIGN. The manufacture of components (Deck plates being warped and installed with filler), the wrong metal used in rods, and lack of grout and water damage all add up to a problematic picture.
