Senator Chris Dodd (Connecticut) and Senator Chuck Hagel (Nebraska) have introduced the National Infrastructure Bank Act of 2007. The bank would independently select and finance projects with a potential federal investment of at least $75 million. It would be financed with $60 billion in bonds.
The bank is designed to finance select, large projects. It could fund almost any type of public infrastructure (transportation, water, sewer, housing, etc.). It will not replace existing programs.
