Avery County's Poor-condition bridges carry 24,810 vehicle crossings a day

That is 14.5% of the county's reported daily bridge traffic on 9.3% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 2,481 crossings a day against 740 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.

37% of Avery County's bridges have passed the 50-year mark

40 of the 108 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 25.9% 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 30.6% of the county's Poor-condition bridge traffic

NC184 over SHAWNEEHAW CREEK, built 1952, carries 7,600 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 10-bridge count understates how much of the daily burden sits on a single crossing.
