The Interstate 35 Bridge
Doug Ross has aerials of the Interstate 35 Mississippi River Bridge before it's collapse to show the layout. Slide posted a series of photos taken from the ground after the collapse. James Lileks, who runs Buzz.mn has extensive coverage. Noah at Blanked Out lives in sight of the bridge and actually saw it collapse. Here's his account: (Hat tip: Captain Ed, who lives in the area and has wall to wall coverage on the collapse.
Description of collapse: Surprisingly quiet, but my entire warehouse apt shook quite a bit. Bridge fell so very slowly - poof. Yelled and yelled but no one answered. Only a handful of ppl in water, all got out ok and then began to help as well. Ran into woman who thought school bus was trapped on east side in fold of highway. Couldn’t confirm it or get to the other bank to help. ... I live the closest to the 35W Bridge than anyone in Minneapolis and I watched it come down from my roof.
I spent 20mins getting people out and off the bridge. I’m being evacuated.
PS This was not a bomb.
