It is thus suprising when we look at the issue of dangerous bridges. The most prominent bridge collapse was of course that in Minnesota in 2007 in which many people died and even more were injured. http://www.maryland-law.com/blog/dangerous-bridges-where-are-they.cfm
Despite this deadly and catstrophic event, the issue of bridge integrity is very real and little discussed.
To put this matter in perspective 12% of all bridges in the United States are "structurally deficient". In Maryland, 396 brdiges are "structurally deficient" and in the District of Columbia the number is 20, a national low. It is nice to see our hometown at a nation's best on something.
The most disturbing state is Pennsylvania with more than 6,000 "structurally deficient" bridges or more than 27%.
