Wyoming County, Pennsylvania contains 140 public highway bridges. Roughly 42.1% are rated “Good,” 35% “Fair,” and 22.9% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.

Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county.

Wyoming County's Poor-condition bridges carry 16,666 vehicle crossings a day

That is 7% of the county's reported daily bridge traffic on 22.9% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 521 crossings a day against 2,061 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.

52.9% of Wyoming County's bridges have passed the 50-year mark

74 of the 140 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 42.1% 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 14.4% of the county's Poor-condition bridge traffic

SR 0092 TR 92 over HORTON CREEK, built 1969, carries 2,397 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 32-bridge count understates how much of the daily burden sits on a single crossing.
