Presque Isle County's Poor-condition bridges carry 642 vehicle crossings a day
That is 2.1% of the county's reported daily bridge traffic on 10.8% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 161 crossings a day against 665 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.

48.6% of Presque Isle County's bridges have passed the 50-year mark
18 of the 37 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 43.2% 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 47% of the county's Poor-condition bridge traffic
SCHUBERT HIGHWAY over MONAGHAN CREEK, built 1960, carries 302 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 4-bridge count understates how much of the daily burden sits on a single crossing.
