Hood River County's Poor-condition bridges carry 13,699 vehicle crossings a day

That is 2.9% of the county's reported daily bridge traffic on 2.4% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 6,850 crossings a day against 3,485 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.

56.1% of Hood River County's bridges have passed the 50-year mark

46 of the 82 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 48.8% 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 93.9% of the county's Poor-condition bridge traffic

I-84 White Salmon over COLUMBIA RIVER, built 1924, carries 12,861 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 2-bridge count understates how much of the daily burden sits on a single crossing.
