Share of 234 NBI-tracked bridges by lowest applicable component rating.
That is 9.1% of the county's reported daily bridge traffic on 5.8% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 124 crossings a day against 73 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.

5 of the 234 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 56.8% 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.

CRAIG/KLAWOCK/HOLL over CRAB CREEK CULVERT, built 1985, carries 1,200 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 16-bridge count understates how much of the daily burden sits on a single crossing.
