Beaver County, Pennsylvania contains 299 public highway bridges. Roughly 41.1% are rated “Good,” 48.8% “Fair,” and 10% “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.

Beaver County's Poor-condition bridges carry 136,827 vehicle crossings a day

That is 7.3% of the county's reported daily bridge traffic on 9.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 4,887 crossings a day against 3,302 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.

Computed over the 297 of 299 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

54.5% of Beaver County's bridges have passed the 50-year mark

163 of the 299 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 41.1% 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 16.6% of the county's Poor-condition bridge traffic

PA TPK (I-76) over SR 1001 BEAVER RIV RR, built 1952, carries 22,663 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 30-bridge count understates how much of the daily burden sits on a single crossing.
