Bridge jam-packed collapses bringing tourists down into water

Has this been shared on ats already?

Its amazing it was captured, wonder by a stationary cam or what..

That's Chinese building codes for ya...

Everyone wants to build a bridge and put their name on it, no one wants to take care of infrastructure..

CHINA – The collapse of a pedestrian bridge at a tourist spot in eastern China sent dozens of people into the water below.

Most people managed to scramble up the sides of the bridge, while park officials threw life preservers to those treading water.

Ten people were hurt and taken to the hospital. Why the bridge gave way is being investigated.

Tourists ? They all seemed to be in a pretty big rush for tourists.
Chinese tourists that don't seem interested in snapping pictures?
Somethings a miss. And why the bridge gave way is completely
obvious.

Ya I don't think I would walk across that bridge with 100 other people packed on it.... They have NO patience whatsoever

I drive over this bridge in the town where I live and if I am stopped on it I can feel it rock up and down. It freaks me out. I will sometimes roll my window down - just in case. I've heard if it rocks it's good though so I try to keep that in mind when it makes me feel nervous.

The small bounce is normal. Bridges are built with a slight arch (not visible) as well as having expansion joints to account for hot / cold / snow / ice / etc.

I would be more concerned if a bridge did not have the slight bounce.

I was looking at frames 23 to 26 and you can see on
the side closest to the camera, the stress becomes to much
for the hand rail. Once the handrail is defeated? Well
at least they weren't over a gorge. Also investigators
will notice that the hand rail relents directly above where
the diagonal support tubes are welded. This could mean
a weak weld, the most doubtful. The top handrail was
weakened by heat at the time of welding, only a little
less doubtful. The weld was allowed to rust do to low
maintenance. Someone most certainly knew this was going
to happen sooner or later and just wanted to see everyones
ass get dumped in the river. This would account for the
camera.

This shows us that a high quality system of nuts and bolts
is better than welds. You get ample warning from nuts that
become loose. So the vid exemplifies the difference quite well.
Nuts and bolts are easily maintained and replaced.

My son's an engineering student, and last year showed me this video, which he said they used as an example in his class of everything not to do when designing a bridge.

Yes, a little sway is good, but...
