Cabo Rojo County's Poor-condition bridges carry 37,700 vehicle crossings a day
That is 31.1% of the county's reported daily bridge traffic on 28.6% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 6,283 crossings a day against 4,733 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.

47.6% of Cabo Rojo County's bridges have passed the 50-year mark
10 of the 21 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 28.6% 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 22% of the county's Poor-condition bridge traffic
PR 103 over BOQUERON CREEK, built 1933, carries 8,300 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.
