Jackson County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Jackson County ranks #18 of 82 Mississippi counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 2.6%). Jackson County, Mississippi contains 268 public highway bridges. Roughly 69.4% are rated “Good,” 28% “Fair,” and 2.6% “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.

Jackson County's Poor-condition bridges carry 23,710 vehicle crossings a day
That is 1.6% of the county's reported daily bridge traffic on 2.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,387 crossings a day against 5,346 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 268 of 268 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
11.2% of Jackson County's bridges have passed the 50-year mark
30 of the 268 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 69.4% 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 40.5% of the county's Poor-condition bridge traffic
HANSHAW ROAD over DAVIS BAYOU, built 1991, carries 9,600 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 7-bridge count understates how much of the daily burden sits on a single crossing.
