Jack County's Poor-condition bridges carry 100 vehicle crossings a day
That is 0.1% of the county's reported daily bridge traffic on 0.7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 100 crossings a day against 615 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.

60.7% of Jack County's bridges have passed the 50-year mark
82 of the 135 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 44.4% 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 100% of the county's Poor-condition bridge traffic
CAMPSEY RD- PCT 1 over TRIB OF CROOKED CREEK, built 1935, 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 1-bridge count understates how much of the daily burden sits on a single crossing.
