Poweshiek County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Poweshiek County, Iowa contains 221 public highway bridges. Roughly 22.6% are rated “Good,” 30.8% “Fair,” and 44.3% “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.
