Crawford County's Poor-condition bridges carry 84,924 vehicle crossings a day

That is 11.7% of the county's reported daily bridge traffic on 17.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,213 crossings a day against 1,667 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.

60.4% of Crawford County's bridges have passed the 50-year mark

241 of the 399 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 35.6% 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.

Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.

One structure carries 12.4% of the county's Poor-condition bridge traffic

SR 6 GRAND ARMY HY over OVER WATSON RUN, built 1939, carries 10,524 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 70-bridge count understates how much of the daily burden sits on a single crossing.
