Monroe County, Pennsylvania contains 315 public highway bridges. Roughly 26.3% are rated “Good,” 52.7% “Fair,” and 21% “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.

Monroe County's Poor-condition bridges carry 225,529 vehicle crossings a day
That is 9.1% of the county's reported daily bridge traffic on 20.7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,470 crossings a day against 4,476 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.

73% of Monroe County's bridges have passed the 50-year mark
230 of the 315 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 26.3% 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 9.1% of the county's Poor-condition bridge traffic
US 209 (LR 461 W) over MARSHALLS CREEK, built 1930, carries 20,446 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 66-bridge count understates how much of the daily burden sits on a single crossing.
