Yakutat City and County's Poor-condition bridges carry 457 vehicle crossings a day

That is 16.5% of the county's reported daily bridge traffic on 8.3% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 457 crossings a day against 224 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.

26.7% of Yakutat City and County's bridges have passed the 50-year mark

4 of the 15 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 46.7% 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.

One structure carries 100% of the county's Poor-condition bridge traffic

IRR:OCEAN CAPE RD over ANKAU SLOUGH, built 1961, carries 457 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.
