FHWA NBI record, refreshed with each annual release.
PERIMETER RD in Chatham, Georgia sits above 71% of rated Georgia bridges on inventory load rating (33 t), while its 1953 build year is earlier than 95% of Chatham's recorded-year cohort (265 bridges).
PERIMETER RD in Chatham, Georgia is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1953, it carries 1 rated component on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.

FHWA NBI Program ↗How to read this record
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 Chatham and across Georgia. Georgia 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.
