U.S. infrastructure crumbling as Congress debates funding

Harrisburg, Pennsylvania — The aging 61-year-old South Bridge in central Pennsylvania is one of 12,000 in the state that needs repair. On several other bridges, CBS News discovered rust, cracks and some closed bridges waiting for fixes. 

The American Society of Civil Engineers gave Pennsylvania a C- on its infrastructure report card.  "A lot of our bridges were built in the '50s and the '60s, which just means that they're reaching the end of their useful life," said Cathy Farrell, the American Society of Civil Engineers Pennsylvania infrastructure report card chair. "Unfortunately, people only realize that infrastructure isn't working when it breaks."
