The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Monroe County posts a better-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, Monroe County ranks #32 of 82 Mississippi counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 4.1%). Monroe County, Mississippi contains 290 public highway bridges. Roughly 64.5% are rated “Good,” 31.4% “Fair,” and 4.1% “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 290 NBI-tracked bridges by lowest applicable component rating.
That is 0.7% of the county's reported daily bridge traffic on 4.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 386 crossings a day against 2,519 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 290 of 290 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
55 of the 290 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 64.5% 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.
HATLEY-SMITHVILLE over WEAVER CREEK, built 1954, carries 1,800 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 12-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 4,637 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.

The 5 Mississippi counties nearest Monroe County in number of bridges, with their condition splits. Its 4.1% Poor share is the 2nd-lowest of these 6. Its average build year of 1989 against a peer-group mean of 1985 is in line with the group.
