Frequently Asked Questions

The National Bridge Inventory (NBI) is a federal database maintained by the Federal Highway Administration containing inspection data for all bridges on public roads in the U.S. with a span of more than 20 feet. Bridge owners must inspect each structure at least every 24 months.

ADT stands for Average Daily Traffic — the average number of vehicles crossing the bridge per day. Bridges are sorted by ADT by default because high-traffic bridges in poor condition pose the greatest risk to the most people.

Yes. Use the search field above to find bridges by name, location, or features crossed. You can also combine the search with state and condition filters to narrow your results.
