Lancaster County's Poor-condition bridges carry 160,220 vehicle crossings a day

That is 3.3% of the county's reported daily bridge traffic on 4.9% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 5,007 crossings a day against 9,043 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 659 of 661 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

31% of Lancaster County's bridges have passed the 50-year mark

205 of the 661 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 56.3% 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 20.5% of the county's Poor-condition bridge traffic

SB-I180/US34 over I80, built 1960, carries 32,795 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.
