Bedford County, Pennsylvania contains 417 public highway bridges. Roughly 30% are rated “Good,” 60.9% “Fair,” and 9.1% “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.

Bedford County's Poor-condition bridges carry 100,875 vehicle crossings a day

That is 6.3% of the county's reported daily bridge traffic on 8.9% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,726 crossings a day against 1,130 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.

64.3% of Bedford County's bridges have passed the 50-year mark

268 of the 417 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 30% 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 35.9% of the county's Poor-condition bridge traffic

PA TPK (I-70&I-76) over SR 2019(LR 05036), built 1939, carries 36,252 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 38-bridge count understates how much of the daily burden sits on a single crossing.
