Among the most "notable" infrastructure failures in the U.S. in recent years are the collapse of the Skagit Bridge in Washington state in May; the 2010 collapse of the Metrodome roof in Minneapolis, and the collapse of a ceiling in a tunnel of Boston's Big Dig in 2006, according to this slide show. Also included are the 2005 failure of the Taum Sauk reservoir in Missouri and the breaches of New Orleans' levees and canals after Hurricane Katrina in 2005. Upgrading and repairing infrastructure is expensive and governments at all levels are struggling to find ways to pay for it, this article notes.
