Lyon County, KS

493 public highway bridges

Lyon County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Lyon County, Kansas contains 493 public highway bridges. Roughly 59.6% are rated “Good,” 31.2% “Fair,” and 1% “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.
