Carlisle County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Carlisle County ranks #10 of 120 Kentucky counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 2.7%). Carlisle County, Kentucky contains 74 public highway bridges. Roughly 35.1% are rated “Good,” 62.2% “Fair,” and 2.7% “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.

Carlisle County's Poor-condition bridges carry 227 vehicle crossings a day
That is 0.4% of the county's reported daily bridge traffic on 2.7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 114 crossings a day against 593 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.

48.6% of Carlisle County's bridges have passed the 50-year mark
36 of the 74 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 35.1% 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 73.6% of the county's Poor-condition bridge traffic
KY-1203 over GRAY CREEK, built 1968, carries 167 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 2-bridge count understates how much of the daily burden sits on a single crossing.
