Dodge County's Poor-condition bridges carry 40,380 vehicle crossings a day

That is 7.7% of the county's reported daily bridge traffic on 3.6% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 3,365 crossings a day against 1,466 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.

39.2% of Dodge County's bridges have passed the 50-year mark

131 of the 334 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 71% 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 23.7% of the county's Poor-condition bridge traffic

BELL ST over UPRR 191-707-E, built 1994, carries 9,570 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 12-bridge count understates how much of the daily burden sits on a single crossing.
