Walthall County's Poor-condition bridges carry 160 vehicle crossings a day
That is 0.1% of the county's reported daily bridge traffic on 1.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 80 crossings a day against 769 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.

23.4% of Walthall County's bridges have passed the 50-year mark
36 of the 154 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 85.7% 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 62.5% of the county's Poor-condition bridge traffic
ROBEY JEFFERSON RD over BRANCH OF MAGEES CREEK, built 1970, carries 100 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 2-bridge count understates how much of the daily burden sits on a single crossing.
