Wilson County's Poor-condition bridges carry 666 vehicle crossings a day

That is 0.1% 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 222 crossings a day against 3,408 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.

57.6% of Wilson County's bridges have passed the 50-year mark

80 of the 139 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 67.6% 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.

One structure carries 80.5% of the county's Poor-condition bridge traffic

FM 1107 over ECLETO CREEK, built 1970, carries 536 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 3-bridge count understates how much of the daily burden sits on a single crossing.
