Preston County's Poor-condition bridges carry 47,920 vehicle crossings a day

That is 26.6% of the county's reported daily bridge traffic on 23.1% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 1,141 crossings a day against 421 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.

48.4% of Preston County's bridges have passed the 50-year mark

88 of the 182 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 35.2% 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 13.7% of the county's Poor-condition bridge traffic

INTERSTATE 68 WB over Laurel Run & Co Rt 73/5, built 1970, carries 6,550 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 42-bridge count understates how much of the daily burden sits on a single crossing.
