Guánica County, Puerto Rico contains 25 public highway bridges. Roughly 12% are rated “Good,” 84% “Fair,” and 4% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.

Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county.

Guánica County's Poor-condition bridges carry 24,400 vehicle crossings a day

That is 7% of the county's reported daily bridge traffic on 4% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 24,400 crossings a day against 5,508 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 25 of 25 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

16% of Guánica County's bridges have passed the 50-year mark

4 of the 25 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 12% 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 100% of the county's Poor-condition bridge traffic

PR 2 over CRISTAL CREEK, built 1979, carries 24,400 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 1-bridge count understates how much of the daily burden sits on a single crossing.
