Crenshaw County's Poor-condition bridges carry 575 vehicle crossings a day
That is 0.4% of the county's reported daily bridge traffic on 1.8% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 192 crossings a day against 879 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.

43.3% of Crenshaw County's bridges have passed the 50-year mark
74 of the 171 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 45% 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 96.5% of the county's Poor-condition bridge traffic
COUNTY ROAD 11 over BEAVER BRANCH RELIEF, built 1961, carries 555 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.
