Wyoming County's Poor-condition bridges carry 48,150 vehicle crossings a day

That is 37.2% of the county's reported daily bridge traffic on 33.1% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 908 crossings a day against 1,168 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.

21.3% of Wyoming County's bridges have passed the 50-year mark

34 of the 160 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 3.1% 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.

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

One structure carries 11.8% of the county's Poor-condition bridge traffic

WV 16 over SLAB FORK, built 1985, carries 5,700 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 53-bridge count understates how much of the daily burden sits on a single crossing.
