All you MN Dweb'ers OK?

I saw that on the news last night, wondering if I could drive off the broken stuff in my LR. Some sections no, but other sections look like Land Rover terrain to me! Hope you guys are OK.

:rofl:
I was surprised to see the entire span of the bridge laying flat in the river, with vehicles still standing upright on it. It means that the entire structure collapsed nearly at the same instant - not just a pylon.
Wonder if all that salt off the road corroded every seam and rivet in that trestle...

That sure wasn't a good thing to happen. The whole mess sounds funny to me. I'm interested to find out what brought it down.

:rofl: :rofl: Someone has posted on youtube "Minneapolis Bridge Collapses - Live Cellphone Footage"
Only problem is, it's the Tacoma Narrows Bridge collapse in 1940 :smilelol:

oh yeah, Tacoma Narrows... Minneapolis bridge is bound to become another engineering textbook case.
Here is supposed live video of it collapsing. CNN has a better link, but I can't find it now.

i just love how news anchors became structural engineers instantly. i do alot of structural concrete construction and even with my MINIMAL knowledge of bridges, their conclusions were hilarious. one anchor even suggested the heat of the day may have caused it. you know, since it was made of wax.... Gretta Van Sustern (sp)'s insight was deep, it went like "its supposed to be over the water....but....its not.....its in the water."
Dang, we haven't heard from Garrick "Rik" Olsen yet have we?
I don't recall the newspaper he writes for ... lemme go look

. . . The Star Trribune points out another issue that led to the collapse. The bridge's design and construction in the 1960s is a potentially critical factor, not for its age but for the philosophy of design at the time. Samuel Schwartz, who closed his share of bridges in New York City, explains that bridges built before and after that period have redundancies designed into them. Not so with the post-war period going into the 1960s, however, when American builders and government officials felt that bridges had been overdesigned and excesively costly. After a number of collapses in the 1970s, the designs went back to redundancies -- but apparently no one thought to add to the existing bridges, even those high-traffic structures like the I-35W bridge. . . .
Edit add - Also, MN highway department funding from the Feds has been increased 46%. This was not a funding or failing infrastructure issue.
