San Germán County's Poor-condition bridges carry 69,950 vehicle crossings a day

That is 17.4% of the county's reported daily bridge traffic on 20% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 7,772 crossings a day against 15,764 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.

Computed over the 45 of 45 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

51.1% of San Germán County's bridges have passed the 50-year mark

23 of the 45 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 26.7% 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.

Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.

One structure carries 54.3% of the county's Poor-condition bridge traffic

PR 2 over CAIN RIVER, built 1964, carries 38,000 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 9-bridge count understates how much of the daily burden sits on a single crossing.
