I was late on the uptake on this one due to an failure with the internets at my home, but apparently the I35W bridge in Minneapolis just fell into the river.

Here is some satellite imagery of the bridge before the collapse (it's the big one on the left). For those that aren't familiar with MSP, that's a pretty tall bridge, and it's one of the main arteries to downtown Minneapolis. And it fell down at about 18:05; there was probably a lot of traffic on it at the time. Not good. Anyway, now it looks like this:

Goooo...

Those of you into urban exploration will recognize the massive entrance to the I35 drainage tunnel in the first image... Those of you into not falling into rivers will recognize that the second image represents a pretty bad day for a lot of people.
