Daviess County's Poor-condition bridges carry 10,751 vehicle crossings a day

That is 9.4% of the county's reported daily bridge traffic on 24.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 199 crossings a day against 582 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.

50.9% of Daviess County's bridges have passed the 50-year mark

113 of the 222 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 27.5% 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 68.4% of the county's Poor-condition bridge traffic

IS 35 N over GRAND RVR, built 1976, carries 7,358 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 54-bridge count understates how much of the daily burden sits on a single crossing.
