Much of U.S. infrastructure, especially in and around the cities, is slowly failing. Each year, for example, more and more water mains are leaking and breaking. Many of them were installed 80 to 100 years ago. Bridges are another example of aging infrastructure that requires increasing maintenance and/or replacement. I don't think there is really a full grasp on the magnitude of the problem or costs.
