Crumbling infrastructure

From roads to dams to bridges and sewer systems, America's infrastructure is falling apart.

Fixing these problems and others threatening the nation's critical infrastructure would cost $1.6 trillion -- more than half of the annual federal budget, the American Society of Civil Engineers (ASCE) estimates. And that doesn't include what it will cost for new capacity to serve a growing population.

The numbers are staggering.

Bridges

More than one in four of America's nearly 600,000 bridges need significant repairs or are burdened with more traffic than they were designed to carry, according to the U.S. Department of Transportation.
