The Worst Bridge Collapses in Last 100 Years

On August 1, 2007, the Interstate -35 westbound bridge over the Mississippi River in Minneapolis came tumbling down during the evening rush hour, killing 13 and injuring 145.  The incident brought the crumbling infrastructure of the US to the front of the news, but as usual, little if anything was done about it.  Bridges have been falling as long as men have built them.  The sorry state of repair and maintenance of American bridges means more deadly failures are likely to occur, sooner rather than later.  Here we list 10 notable bridge failures, not necessarily the deadliest or most famous, but ones we hope you find interesting due to the varied reasons for collapse. What other bridge failures would you include in this list?
