Prince William County's Poor-condition bridges carry 127,052 vehicle crossings a day
That is 2.5% of the county's reported daily bridge traffic on 1.3% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 31,763 crossings a day against 13,875 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.

25.7% of Prince William County's bridges have passed the 50-year mark
78 of the 303 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 54.5% 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 59.8% of the county's Poor-condition bridge traffic
INTERSTATE RT.95SB over NEABSCO CREEK, built 1963, carries 75,952 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 4-bridge count understates how much of the daily burden sits on a single crossing.
