Clinton County's Poor-condition bridges carry 563 vehicle crossings a day

That is 1.4% of the county's reported daily bridge traffic on 7.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 188 crossings a day against 2,373 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.

61% of Clinton County's bridges have passed the 50-year mark

25 of the 41 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 17.1% 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.

One structure carries 50.3% of the county's Poor-condition bridge traffic

KY-1576 over SPRING CREEK, built 1969, carries 283 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 3-bridge count understates how much of the daily burden sits on a single crossing.
