Scioto County's Poor-condition bridges carry 13,111 vehicle crossings a day

That is 1.4% of the county's reported daily bridge traffic on 5.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 690 crossings a day against 2,013 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.

Computed over the 376 of 376 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

34.3% of Scioto County's bridges have passed the 50-year mark

129 of the 376 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 65.7% 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.

Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.

One structure carries 17.8% of the county's Poor-condition bridge traffic

CAREYS RUN-POND CK over CAREYS RUN RD(CAREYS RUN, built 1940, carries 2,339 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 19-bridge count understates how much of the daily burden sits on a single crossing.
