FHWA NBI record, refreshed with each annual release.
PERIMETER RD. in Guaynabo, Puerto Rico sits above 43% of rated Puerto Rico bridges on inventory load rating (33 t), while its 1947 build year is earlier than 92% of Guaynabo's recorded-year cohort (63 bridges).
PERIMETER RD. in Guaynabo, Puerto Rico is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1947, it carries 1 rated component on the inspecting agency's 0-9 scale, and its weakest reported component scores 5. The lowest applicable rating sets the federal condition category, so this Fair result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.

This page shows what the last federal inspection recorded, not whether PERIMETER RD. is safe to cross today. Here is how to use it.
- NBI condition ratings reflect the latest record in this annual dataset, not a live status. Current routine inspection intervals are risk-based.
- Learn how the 0–9 condition scale and Good/Fair/Poor categories are defined. How condition ratings work
- Compare PERIMETER RD. against other structures in Guaynabo and across Puerto Rico. Puerto Rico bridges
- Noticed visible damage or a safety concern? Report it to the agency that owns the bridge, or call 911 in an emergency. How to report a bridge
Condition codes come straight from the FHWA National Bridge Inventory and are not a real-time safety judgment. Only the owning agency, a state DOT, county, or other owner, can post, restrict, or close a bridge.
