Thanks, remind and Michelle.The bridge was apparently inspected twice in the last two years and it passed inspection. So, either something recently has happened to the bridge's integrity or the inspections were not done properly. It reminds me of the earthquake in San Francisco about 15 years ago when portions of the double-decker bridge (the Bay Bridge) collapsed. My sister lived in the Bay Area at the time. She was driving my brother back from the airport and had a choice of taking either the Bay Bridge or the San Mateo Bridge back home (the choices were equidistant). As it turned out, she chose the San Mateo Bridge and she was on that bridge when the earthquake happened. Just dumb luck. The bridge that collapsed last night is part of the I-35 interstate freeway that runs from Duluth, MN all the way down to Texas. It will take at least a couple of years—and probably a $100 million—to build a new bridge. In the mean time, it’s going to be a transportation nightmare.

It is no joke for those living there and other places where bridges and crucial levees were not upgraded and repaired.
Obviously you didn't read the post very carefully. Otherwise, how do you square your comment: quote: people's right to safety are being eroded because our money is being spent on things we never signed up for.
with this comment: quote: Maybe Americans will stand and stop identifying themselves as war mongers and get their home affairs in order?
There's a world of difference between 'things we never signed up for' and implying that all Americans are 'war mongers' who have purposely ignored domestic problems. I'm sorry, but I still saw this as a case of someone seeing a tragedy and immediately having a knee-jerk reaction of blaming Americans for being 'warmongers' and essentially saying 'you got what you deserved'.

Haven't they? quote: I'm sorry, but I still saw this as a case of someone seeing a tragedy and immediately having a knee-jerk reaction of blaming Americans for being 'warmongers' and essentially saying 'you got what you deserved'.
Actually, there is a world of difference between what was said and what you are trying to infer. My point was they need to refocus their gaze upon their country which is falling apart, as opposed to allegedly trying to fix other country's problems, while really spending trillions to destroy them. I would say the same thing about Canada too, as a matter a fact.

quote: Originally posted by Stockholm: We had a highway overpass collapse outside of Montreal recently killing four people, so obviously there are plenty of infrastructure problems in Canada too.
This came to mind when I was watching the Minneapolis bridge collapse coverage the other night, when they said the bridge was 40 years old. I think the overpass in Quebec was about the same age.
And it seems to me that much of our infrastructure was built during the 50's and 60's. One report had engineers pointing out that those bridges are now carrying more traffic than original design specifications called for. And there is my pet hypothesis that the increased desire for safety has us putting loads more salt on reinforced concrete and steel girder structures than the original designers planned for. Put the increased traffic loads and increased corrosion together, and the original lifespans of these bridges might be significantly reduced. In London, Ontario, work has been underway on the Highbury ave and Adelaide street overpasses that soar over the CN rail yards. This spring some mysterious work was done on the cement pillars that support the Quebec street overpass that elevates one over the CP yard. Back some years ago, when I was still ridding my ten speed to work, I hit the Quebec street overpass. The bridge had slipped at the expansion joint, leaving a four inch "bump" as the warning sign euphamised. If you walk under the bridge that connects Queen's ave with Riverside, right at the Forks, one can see deep cracks in the cement. Not being an engineer, I don't know if they are significant or not. At alt.london, someone keeps drawing attention to a rusted hole through the box girder bridge that CN has over Wharcliffe road at Springbank.
