County profile · official public datasets
201 public highway bridges tracked in the FHWA National Bridge Inventory: 72.1% rated Good, 22.9% Fair, 5% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Marion County posts a higher-than-median Poor-condition share among rated counties in the state across mid-size county bridge inventory.
Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Marion County ranks #43 of 82 Mississippi counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 5%). Marion County, Mississippi contains 201 public highway bridges. Roughly 72.1% are rated “Good,” 22.9% “Fair,” and 5% “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.

Share of 201 NBI-tracked bridges by lowest applicable component rating.
That is 2.5% of the county's reported daily bridge traffic on 5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 804 crossings a day against 1,792 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.

52 of the 201 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 72.1% 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.
N MAIN ST/OLD 13 N over DRY CREEK, built 1960, carries 6,500 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 10-bridge count understates how much of the daily burden sits on a single crossing.
