States with similar infrastructure profiles, ranked by percentage of bridges in poor condition.
Grading: Grades are based on the percentage of bridges classified as "poor condition." A bridge is in poor condition when at least one major component (deck, superstructure, or substructure) is rated 4 or below on the NBI 0-9 scale.
Data Source: Federal Highway Administration (FHWA) National Bridge Inventory (NBI). Data is updated annually. BridgeStats is not affiliated with or endorsed by the FHWA.
Watchlist Criteria: Bridges with any component rated "5" (Fair) are one step from the poor threshold of 4 and are flagged for monitoring. These bridges are not yet in poor condition but may deteriorate without maintenance.
