Mayors ask Congress to help fix U.S. infrastructure

Big-city mayors told Congress on Thursday that they are overwhelmed by the infrastructure needs of their regions and cannot maintain well-functioning water systems, roads and rail networks without more federal help.

"We're having a quiet collapse of prosperity," said Kansas City, Missouri, Mayor Mark Funkhouser, one of four mayors to testify before the Senate Banking Committee about the state of the nation's infrastructure, which they agreed was poor and getting worse.
