According to the Federal Highway Administration's 2024 National Bridge Inventory, Sanders County, Montana contains 116 public highway bridges. Roughly 37.9% are rated “Good,” 54.3% “Fair,” and 7.8% “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.
