Berks County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Berks County ranks #49 of 67 Pennsylvania counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 15%). Berks County, Pennsylvania contains 667 public highway bridges. Roughly 21.4% are rated “Good,” 63.6% “Fair,” and 15% “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.

Berks County's Poor-condition bridges carry 312,870 vehicle crossings a day

That is 5.6% of the county's reported daily bridge traffic on 15% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,129 crossings a day against 6,540 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 666 of 667 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

68.1% of Berks County's bridges have passed the 50-year mark

454 of the 667 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 21.4% 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 26.3% of the county's Poor-condition bridge traffic

SR 422 (LR793) over THUN RECREATIONAL TRAIL, built 1963, carries 82,168 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 100-bridge count understates how much of the daily burden sits on a single crossing.
