Loíza County's Poor-condition bridges carry 16,400 vehicle crossings a day
That is 42.1% of the county's reported daily bridge traffic on 60% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 5,467 crossings a day against 10,300 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.

60% of Loíza County's bridges have passed the 50-year mark
3 of the 5 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 20% 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 50% of the county's Poor-condition bridge traffic
PR 187 over GRANDE DE LOIZA RIVER, built 1985, carries 8,200 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 3-bridge count understates how much of the daily burden sits on a single crossing.
