What is BridgeReport.org?

Free access to federal bridge inspection data. We transform the National Bridge Inventory (NBI) — containing inspection records for every US highway bridge — into searchable, easy-to-understand reports for citizens, journalists, researchers, and officials.

How bridges are rated: Federal law requires inspection of every highway bridge at least every 24 months. Inspectors rate deck, superstructure, and substructure on a 0-9 scale. A rating of 4 or below classifies a bridge as "poor condition" — not unsafe, but prioritized for repair.

What you can do here: Check bridges in your area, compare states and counties, explore historic landmarks, find record-breaking structures, or embed data on your website. All data comes directly from FHWA.

Bridge inspection data is typically updated every 24 months. Conditions may have changed since the last inspection.

“Structurally deficient” does not mean a bridge is unsafe or likely to collapse. It indicates that one or more key structural elements are in poor or worse condition. Bridges are inspected regularly and may have load restrictions in place.
