Perry County's Poor-condition bridges carry 2,846 vehicle crossings a day

That is 0.8% of the county's reported daily bridge traffic on 4.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 356 crossings a day against 1,650 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.

38.6% of Perry County's bridges have passed the 50-year mark

68 of the 176 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 42% 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 65.9% of the county's Poor-condition bridge traffic

KY-80 over RT. FK. BIG CREEK, built 1928, carries 1,875 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 8-bridge count understates how much of the daily burden sits on a single crossing.
