Casey County's Poor-condition bridges carry 16,916 vehicle crossings a day

That is 15% of the county's reported daily bridge traffic on 7.7% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 1,538 crossings a day against 990 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.

43.4% of Casey County's bridges have passed the 50-year mark

62 of the 143 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 14.7% 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.

One structure carries 53.7% of the county's Poor-condition bridge traffic

US-127 over GREEN RIVER IN LIBERTY, built 1957, carries 9,092 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 11-bridge count understates how much of the daily burden sits on a single crossing.
