Monongalia County's Poor-condition bridges carry 927,950 vehicle crossings a day
That is 51.9% of the county's reported daily bridge traffic on 19.8% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 23,199 crossings a day against 4,323 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.

40.9% of Monongalia County's bridges have passed the 50-year mark
83 of the 203 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 36.9% 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 64.7% of the county's Poor-condition bridge traffic
MON CO RT 19/25 over SCOTTS RUN, built 1930, carries 600,500 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 41-bridge count understates how much of the daily burden sits on a single crossing.
