The latest data available is the 2015 National Bridge Inventory. The data is created locally and compiled by the Federal Highway Administration, so the status of some bridges may have changed since the inspection referenced here. Some location data may not be exact and some location information may not be available for some small bridges. Federal rules govern the inspections, but inspections are generally done locally, so each inspector may reach different conclusions. New bridges or bridges that have been recently rebuilt are not classified as either “structurally deficient” or “functionally obsolete,” so they would not be included here. Only counties with bridges are included.
