Juncos County's Poor-condition bridges carry 114,800 vehicle crossings a day

That is 18.3% of the county's reported daily bridge traffic on 21.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 19,133 crossings a day against 3,400 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.

85.7% of Juncos County's bridges have passed the 50-year mark

24 of the 28 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 3.6% 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 33.4% of the county's Poor-condition bridge traffic

PR 30 EASTBOUND over VALENCIANO RV. & L., built 1971, carries 38,350 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 6-bridge count understates how much of the daily burden sits on a single crossing.

Share is of the 114,800 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
