National Bridge Inventory

The U.S. Department of Transportation's Federal Highway Administration National Bridge Inventory database lists structural evaluations and codes for all bridges in the U.S. For the most recent year, 2015, the data includes bridges on highways, railroads, pedestrian-bicycle bridges, overpasses and those designated as historically significant. In each data file, the records represent the most recent inspection for each bridge (which could be several years ago, or could be the current year).

The data include fields showing the year the bridge was built, how many lanes it has and several key fields that can be used for an overall indication of a bridge's quality. There is also a field that indicates the feature intersected, for example if the bridge goes over a body of water or if it intersects with another highway or roadway

Data is available from 1994 - 2015.
