Buncombe County's Poor-condition bridges carry 267,310 vehicle crossings a day

That is 4.7% of the county's reported daily bridge traffic on 7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 6,854 crossings a day against 8,377 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 555 of 555 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

50.8% of Buncombe County's bridges have passed the 50-year mark

282 of the 555 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 34.6% 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 18% of the county's Poor-condition bridge traffic

US19 23 over I-240 OFF RAMPS, built 1968, carries 48,000 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 39-bridge count understates how much of the daily burden sits on a single crossing.
