Hickman County's Poor-condition bridges carry 6,088 vehicle crossings a day

That is 0.7% of the county's reported daily bridge traffic on 5.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 358 crossings a day against 927 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.

36.9% of Hickman County's bridges have passed the 50-year mark

122 of the 331 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 38.7% 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.

Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.

One structure carries 53.9% of the county's Poor-condition bridge traffic

FAS 50 over DUCK RIVER, built 1970, carries 3,281 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 17-bridge count understates how much of the daily burden sits on a single crossing.
