Minneapolis I-35W Bridge Collapse

It’s not local but it’s important: the I-35W bridge across the upper Mississippi River in Minneapolis collapsed today, right in the middle of the Wednesday rush while a Twins-Royals game was going on at the nearby stadium. Erica on our sibling site Metroblogging Minneapolis has 35W Bridge Collapse updates and an open thread right now. Flickr user Adamwolf has photos from on the scene.

Update: Greg has snagged security camera footage catching the bridge collapse, and I’ve made an animated GIF. Just keep following Minneapolis Metroblogging for updates.

    It appears to me that the original structure was a 4 lane bridge (1967), as evidenced by the steel trusses being only 4 lanes wide. I was ivolved in bridge construction in the 70’s in Texas, Louisiana and Mississippi and saw many upgrades where bridge decks were widened with diagonal support members were added to support the extra width. This has even happened where I live (Marble Falls, Tx) where our 2 lane bridge was widened to 4 lanes without any mods to the original structure with the exception of the same diagonal supports tied back to the original structural girters to accomidate the doubling of the road deck. Any comments?
