Lajas County's Poor-condition bridges carry 3,950 vehicle crossings a day
That is 12.1% of the county's reported daily bridge traffic on 33.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,975 crossings a day against 9,100 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.

83.3% of Lajas County's bridges have passed the 50-year mark
5 of the 6 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 16.7% 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 93.7% of the county's Poor-condition bridge traffic
PR 303 over PLANTINA CREEK, built 1960, carries 3,700 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.
