Venango County's Poor-condition bridges carry 15,916 vehicle crossings a day

That is 4.7% of the county's reported daily bridge traffic on 14.8% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 568 crossings a day against 1,310 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.

49.7% of Venango County's bridges have passed the 50-year mark

94 of the 189 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 35.4% 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 50.1% of the county's Poor-condition bridge traffic

SR 62 FRNKN-OIL CT over OVER UPPER TWO MILE RUN, built 1956, carries 7,968 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 28-bridge count understates how much of the daily burden sits on a single crossing.
