"The Crumbling of America" can be seen on The History Channel from 5PM to 7PM (edt) today. This is a HUGE wakeup call. America's infrastructure is collapsing. Tens of thousands of bridges are structurally deficient or functionally obsolete. A third of the nation's highways are in poor or mediocre shape. Massively leaking water and sewage systems are creating health hazards and contaminating rivers and streams. Weakened and under-maintained levees and dams tower over communities and schools. And the power grid is increasingly maxed out, disrupting millions of lives and putting entire cities in the dark. The Crumbling of America explores these problems using expert interviews, on location shooting and computer generated animation to illustrate the kinds of infrastructure disasters that could be just around the bend.
