A eight-lane suspension bridge collapsed in Harbin, northeast China’s Heilongjiang province on August 24, 2012. Three people were killed and five injured when an eight-lane suspension bridge in northeast China collapsed early on August 24, only nine months after it opened, state media said.

Made in China....
: )
“Made in China” stamped on the side.
Courtney Campbell Causeway in Tampa was built by a crook who used salt water while mixing the contrete for the bridges.
Insted of a 60 or 100 year bridge it had to be replaced in twenty.
Course the money he saved made him rich then he filed for bankruptsy and walked away for ever to live large.
Such is the same the world over, poor materials or poor work.
OMG, and they are building bridges in California????
Under 0bama he would be transferred to a foreign post to avoid testifying before Congress.
Guess who made the bridge sections for repairing the Bay Bridge in the SF Bay Area?
makes a person wonder if the Three Gorges Dam would suffer a catastrophic action of events, what would the amount of deaths be, over a hundred million?
From the looks of the pictures, there was to much weight on that bridge from the trucks.
It’s only a guess but I think the cause is right there in your picture. That semi-trailer appears to be filled with gravel. If so it might be close to 50 tons. Add that to a bridge support made with inferior concrete and rebar and you might find a support catastrophically failing.
Anyone who even suggests that China is kicking our butt concerning infrastructure is insane!
It looks like those two trucks hauling gravel might have been overweight for this stretch of road.
Somebody in Pasedena should have consulted an engineer before writing or at least proof read it before publishing it. Those pictures are not of a suspension bridge. As an example, the Golden Gate Bridge is a suspension bridge. This was just an elevated highway.
Others noted that maybe the trucks were too heavy for the roadway. Could be, but as the supports are not as wide as the roadway, I would say that the failure was all of the weight of those trucks were all on one side causing it to fall to that one side, or/and a failure over time and especially suspicious of not doing the proper crush tests of the concrete used.
The road is intact
My theory is the columns eroded evenly from water?
Looks like red truck is hauling bags of rice, not gravel.
Now I see the second truck hauling gravel just in front of the black truck.
They don’t need to beat us. They only need to beat India.
The columns are intact, the caps broke away ... oddly a number of them gave way at the same time.
Faulty concrete used in constructing too large a span of unstressed caps.
My theory
Good point, I’ve seen other pictures from China that show that exact thing happening.
I’ve also seen, (in Person), where a concrete support had too much sand and not enough heavy aggregate or the proper proportion of cement literally shatter when the load it was bearing exceeded it’s capacity.
