Stephenson County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Stephenson County, Illinois contains 332 public highway bridges. Roughly 60.8% are rated “Good,” 32.5% “Fair,” and 2.7% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.
Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.
