Green County, Kentucky contains 57 public highway bridges. Roughly 59.6% are rated “Good,” 28.1% “Fair,” and 12.3% “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.

Green County's Poor-condition bridges carry 2,903 vehicle crossings a day

That is 6.6% of the county's reported daily bridge traffic on 12.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 415 crossings a day against 510 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.

36.8% of Green County's bridges have passed the 50-year mark

21 of the 57 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 59.6% 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 41.7% of the county's Poor-condition bridge traffic

KY-61 over CANEY FORK, built 1928, carries 1,212 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 7-bridge count understates how much of the daily burden sits on a single crossing.
