Wayne County's Poor-condition bridges carry 52,113 vehicle crossings a day

That is 15.5% of the county's reported daily bridge traffic on 31.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 643 crossings a day against 1,217 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.

64.1% of Wayne County's bridges have passed the 50-year mark

166 of the 259 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% 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 15.1% of the county's Poor-condition bridge traffic

SR 0006 TR 6 over MIDDLE CREEK, built 1958, carries 7,850 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 81-bridge count understates how much of the daily burden sits on a single crossing.
