Rockdale County, Georgia contains 44 public highway bridges. Roughly 81.8% are rated “Good,” 15.9% “Fair,” and 2.3% “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.

Rockdale County's Poor-condition bridges carry 45,600 vehicle crossings a day

That is 9.6% of the county's reported daily bridge traffic on 2.3% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 45,600 crossings a day against 9,704 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.

43.2% of Rockdale County's bridges have passed the 50-year mark

19 of the 44 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 81.8% 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

SR 20 over I-20, built 1963, carries 45,600 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.
