Default Oops - Seven dead as US bridge collapses

<http://news.bbc.co.uk/1/hi/world/americas/6927113.stm>

"Seven people have died after a freeway bridge over the Mississippi
river collapsed in the evening rush hour.
At least 60 were injured when part of the I-35W bridge in Minneapolis
fell down at 1805 (2305 GMT) on Wednesday.

Fire Chief Jim Clack told reporters seven died as the structure
buckled, hurling up to 50 vehicles in the water.

The US Department of Homeland Security said there was no reason to
suspect the fall of the bridge, which had been undergoing repairs, was
terror-related."

I know they're only Americans, so we shouldn't feel too bad about it,
but it's certainly not something one sees everyday. Well, unless one
works in the bridge demolition biz.

"The 40-year-old bridge was undergoing repairs at the time of the
accident, and there were reports that construction workers were using a
jackhammer at the time of the collapse." -- Daily Telegraph

It may have been caused by the famous American obesity of the occupants
of the cars. I bet the bridge designers never factored that in.

I wonder if me stubbing my toe on the pavement as I left the house this
morning was terror-related? I must ask the Department of Homeland
Security.

Apparently, because of the size of the drop, it took a while for the cars to
fall into the river. One driver said they counted, "1 Mississippi, 2
Mississippi, 3 Mississippi", as they fell down.

I'll get my coat.

Ah. So being the laughingstock of Europe isn't the _only_ consequence of
the UK's cultural proximity to the United States ...

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Mark Olson <olsonm@tiny.invalid>
saying something like:

IanaCE but I do know how to shear a bolt or two. Anyway, I heard an
eyewitness describe how the shoreside span fell first, the whole
structure wobbled a bit then the main span collapsed. Presumably due to
unbalanced forces in play then.

I live/work 17 miles/7.5 miles from the bridge.

There was also a train going under at the time, which the bridge fell
on (I bet it stopped quick) but I doubt the rumbles from a train, a
drill and one or two lanes of traffic would bring a bridge down that
has been there fore four decades. But I'm not an engineer

If security on 'strategic' locations (airports, embassies, nuclear
installations..) has been 'stepped up' anything like they claim, then this
sort of 'attack' (if it had been one) on 'soft' (i.e. unprotected) targets,
could be expected to i) occur and ii) become more frequent.
