Harrisonburg city County's Poor-condition bridges carry 52,783 vehicle crossings a day
That is 17.9% of the county's reported daily bridge traffic on 14.7% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 10,557 crossings a day against 8,143 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.

52.9% of Harrisonburg city County's bridges have passed the 50-year mark
18 of the 34 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 44.1% 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 28.2% of the county's Poor-condition bridge traffic
ROUTE 33 WBL over I-81, built 1960, carries 14,883 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 5-bridge count understates how much of the daily burden sits on a single crossing.
