• if you are really interested – go look at http://www.nationalbridges.com/ – and you can check the status of any bridge you want – or get a list of the worst bridges in the state, or look at the specs on the 35W bridge.

  There will certainly be other bridge failures – maybe not as spectacular and maybe not in Minnesota – but bridge design in the 60’s was not very good – lots of bridges were constructed without redundant backups – meaning that the failure of a key structural component could cause the entire bridge to fail – and those bridges are all approaching 50 years old.
