Logan County's Poor-condition bridges carry 63,535 vehicle crossings a day

That is 14.4% of the county's reported daily bridge traffic on 23.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,155 crossings a day against 1,777 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.

18.2% of Logan County's bridges have passed the 50-year mark

43 of the 236 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 23.7% 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 19.5% of the county's Poor-condition bridge traffic

US 119 over CSX RAILROAD, built 1972, carries 12,400 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 56-bridge count understates how much of the daily burden sits on a single crossing.
