Now in-house from IRE:
The National Bridge Inventory database lists structural evaluations and codes for all bridges in the U.S. This includes bridges on highways, railroads, pedestrian-bicycle bridges, overpasses and those designated as historically significant. The most recent data includes inspections through December, 2006. Some of the database term definitions are available at: http://www.fhwa.dot.gov/legsregs/directives/fapg/cfr0650d.htm

IRE has also compiled a Resource Page.
