What It Means
The Condition Score combines three NBI component ratings (deck, superstructure, and substructure) with weights of 33%, 33%, and 34% respectively. Each component is rated on a 0-9 scale by federal inspectors. Bridges over 50 years old receive an additional age penalty deduction. The final score maps to letter grades: A (80-100), B (60-79), C (40-59), D (20-39), F (0-19).
