Hickman County's Poor-condition bridges carry 3,844 vehicle crossings a day

That is 6.7% of the county's reported daily bridge traffic on 8.9% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 349 crossings a day against 410 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.

54.5% of Hickman County's bridges have passed the 50-year mark

67 of the 123 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 30.9% 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 44.5% of the county's Poor-condition bridge traffic

US-51 over BRUSH CREEK, built 1926, carries 1,709 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 11-bridge count understates how much of the daily burden sits on a single crossing.
