Dickinson County, Kansas contains 375 public highway bridges. Roughly 47.7% are rated “Good,” 47.2% “Fair,” and 5.1% “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.

Dickinson County's Poor-condition bridges carry 8,612 vehicle crossings a day
That is 3.1% of the county's reported daily bridge traffic on 5.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 453 crossings a day against 834 for a Good-condition one. A Poor rating is a condition category, not a closure or a live safety judgement; it means the lowest applicable component rating is 4 or below.

45.6% of Dickinson County's bridges have passed the 50-year mark
171 of the 375 bridges with a recorded construction year were built in 1974 or earlier. Age alone is not a defect: a well-maintained older bridge can rate Good, and 47.7% of this county's inventory does. Even so, this older cohort is the population from which future Poor ratings are drawn, which is why the age profile below matters alongside the condition split above.
Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.
One structure carries 23.6% of the county's Poor-condition bridge traffic
RS 1816 H15-E8 over MUD CREEK, built 1938, carries 2,035 vehicles a day, the most of any Poor-rated structure here. The county's Poor-condition exposure is concentrated rather than evenly spread, so the 19-bridge count understates how much of the daily burden sits on a single crossing.
