What Is Bridge Condition Rating?
Every bridge in the National Bridge Inventory (NBI) receives an overall condition classification based on the lowest rating of its deck, superstructure, substructure, or culvert components. Each component is rated on a 0–9 scale, where 9 is excellent and 0 is failed.
- Good — All components rated 7 or higher. No structural concerns.
- Fair — Lowest component rated 5 or 6. Minor deterioration but structurally adequate.
- Poor — Lowest component rated 4 or below. Significant deterioration requiring attention. Still safe to drive on, but needs repair or replacement.
A "poor" rating does not mean a bridge is unsafe — it means it has been flagged for priority maintenance or replacement. Unsafe bridges are closed to traffic.
Understanding Bridge Inspections
Federal law requires that most highway bridges be inspected at least every 24 months. Inspectors evaluate the bridge deck, superstructure (beams and supports above the deck), substructure (piers and abutments below), and the waterway channel for scour risk. These inspections determine condition ratings and identify maintenance needs.
