Sevier County, Tennessee contains 273 public highway bridges.

Sevier County's Poor-condition bridges carry 14,518 vehicle crossings a day

That is 0.6% of the county's reported daily bridge traffic on 2.2% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,420 crossings a day against 8,447 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 273 of 273 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

42.9% of Sevier County's bridges have passed the 50-year mark

117 of the 273 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 54.6% 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 54.2% of the county's Poor-condition bridge traffic

NFA B006 over W PRG LITTLE PIGEON RIVE, built 1913, carries 7,870 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 6-bridge count understates how much of the daily burden sits on a single crossing.
