Hurricane Sandy came ashore and morphed into a superstorm, combining with cold air and bringing blizzard conditions over parts of West Virginia and some neighboring Appalachian states. The second-costliest storm in U.S. history crippled New York City's subway system and airports, causing some transportation leaders to question whether the nation's infrastructure can weather such extreme events.

"Each time you replace a bridge, states have to be thinking about not just what kind of traffic demand there is, but how do I make sure this is a bridge that will withstand the future given the erratic weather patterns and climate change we're seeing," Paula Hammond, Washington state's transportation director, told the Associated Press.
