Transylvania County's Poor-condition bridges carry 54,950 vehicle crossings a day

That is 16.4% of the county's reported daily bridge traffic on 13.6% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 2,498 crossings a day against 1,871 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.

46.3% of Transylvania County's bridges have passed the 50-year mark

75 of the 162 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 40.7% 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.

One structure carries 28.2% of the county's Poor-condition bridge traffic

US64 over ABANDONED SOUTHERN RR, built 1966, carries 15,500 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 22-bridge count understates how much of the daily burden sits on a single crossing.
