About Bridge Condition Ratings
Bridge condition ratings are assigned by trained inspectors following Federal Highway Administration guidelines. The overall condition (Good, Fair, or Poor) is based on the lowest rating among the deck, superstructure, and substructure components. Ratings use a 0–9 scale where 9 is excellent and 0 is a failed condition. A "Poor" rating does not mean the bridge is unsafe — it indicates the bridge needs attention, may have load restrictions, or is a priority for maintenance or replacement.
