Macon County, North Carolina contains 223 public highway bridges.

Macon County's Poor-condition bridges carry 43,620 vehicle crossings a day

That is 10.5% of the county's reported daily bridge traffic on 17.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,118 crossings a day against 1,830 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.

65% of Macon County's bridges have passed the 50-year mark

145 of the 223 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 30% 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 43.6% of the county's Poor-condition bridge traffic

US23 441 over RABBIT CREEK, built 1953, carries 19,000 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.
