After shock of bridge’s inexplicable fall at evening rush hour into the country’s largest river, bridge experts offer reassurance – The same federally assigned inspections that show one-quarter of U.S. bridges to be “structurally deficient” or “functionally obsolete,” they are in very little danger of collapsing.

This is what the same experts would have said about the Interstate 35W Bridge in Minneapolis before it collapsed down Wednesday.

Rescue crews searched Mississippi River on Thursday for could be up to 30 more victims beyond the four confirmed dead. It was clear that the bridge’s sudden failure, like the one 40 years ago in West Virginia that inspired the inspection system – could get attention on the country’s decaying bridges.
