Macon County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Macon County ranks #64 of 67 Alabama counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 10.7%). Macon County, Alabama contains 177 public highway bridges. Roughly 24.9% are rated “Good,” 64.4% “Fair,” and 10.7% “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. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

Macon County's Poor-condition bridges carry 39,397 vehicle crossings a day
That is 5.8% of the county's reported daily bridge traffic on 10.7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,074 crossings a day against 1,071 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 177 of 177 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
62.7% of Macon County's bridges have passed the 50-year mark
111 of the 177 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 24.9% 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 79.3% of the county's Poor-condition bridge traffic
I85 over BRANCH, built 1963, carries 31,250 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 19-bridge count understates how much of the daily burden sits on a single crossing.
