Adjuntas County's Poor-condition bridges carry 11,050 vehicle crossings a day

That is 14.6% of the county's reported daily bridge traffic on 15.2% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,210 crossings a day against 5,833 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.

63.6% of Adjuntas County's bridges have passed the 50-year mark

21 of the 33 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 9.1% 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 65.2% of the county's Poor-condition bridge traffic

PR 5516 over WATERWAY, built 1990, carries 7,200 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.

Share is of the 11,050 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
