Since I'll be crossing the new span several times a week, Im certainly hope that we didnt just spend $7B on a POS that could collapse at any moment, and kudos to those who built the original Bay Bridge cantilever section, now that is quality.

And this bridge in China had only been open for 9 months!

A nearly 330-foot-long section of a ramp of the eight-lane Yangmingtan Bridge in the city of Harbin dropped 100 feet to the ground. Four trucks plummeted with it, resulting in three deaths and five injuries...

Questions about the materials used during the construction and whether the projects were properly engineered have been the subject of national debate ever since a high-speed train plowed into the back of a stopped train on the same track on July 23 last year in the eastern city of Wenzhou. The crash killed 40 people and injured 191; a subsequent investigation blamed in particular flaws in the design of the signaling equipment. ..

According to my calculations, and assuming several means 10 times a week, there is a 64% chance that you're going to die on the new Bay Bridge.

Sorry.

What have you got to worry about? If it's "made in China", you know it's not cheap junk.

And you conveniently forget that the chinese infrastructure is pobably 50 times bigger and built very rapidly.. So there will be mistakes. Also you seem to forget that US infrastructure is in pathetic shape and there was a really embarassing bridge collapse in Minneapolis not too long back.

We've caught bad steel from China before which is why the West Dublin BART station took so long to complete. We know what we're doing. Let's cut the sensationalism, shall we? We don't import materials and just slap them into whatever project we're working on without any further analysis.

And you completely disregard that the size of infrastructure has no bearing on quality of engineering.

Japan , and Korea build just as fast , yet they don't cut any corners..... The Bridge Collapse years ago was due to a bad design flaw that was overlooked. Generally alot of things built before 1930 are still in good shape.

I'd be worried. Not only have there been a number of problems with materials, the construction itself has run into issues. There have been concerns that the inspection regime has been tainted. Lots of CYA and a complex web of accountability.

We have the formula for a disaster.
