Bridges are an integral part of the U.S. highway network, providing links across natural barriers, passage over railroads and highways, and freeway connections. The Federal Highway Administration (FHWA) maintains a database of our nation's highway bridges--the National Bridge Inventory (NBI)--with detailed information on all public road bridges greater than 20 feet. This special report gives a brief synopsis of that inventory, including bridge condition and the resources spent for maintenance and upgrades.
