About Poor Condition Bridge Ratings

FHWA rates bridge components on a 0–9 scale. A rating of 4 or below on any major component (deck, superstructure, substructure) classifies the bridge as Poor condition. The bridge remains open to traffic but requires priority attention. Bridges rated 0–2 are immediately closed.
