Jackson County's Poor-condition bridges carry 6,700 vehicle crossings a day

That is 0.7% of the county's reported daily bridge traffic on 1.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,350 crossings a day against 7,748 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.

39.8% of Jackson County's bridges have passed the 50-year mark

49 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 66.7% 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 50.3% of the county's Poor-condition bridge traffic

VALENTINE INDUSTRI over I-85 (SR 403), built 1964, carries 3,370 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.
