County profile · official public datasets
471 public highway bridges tracked in the FHWA National Bridge Inventory: 42% rated Good, 46.9% Fair, 11% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Jasper 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, Jasper County ranks #79 of 115 Missouri counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 11%). Jasper County, Missouri contains 471 public highway bridges. Roughly 42% are rated “Good,” 46.9% “Fair,” and 11% “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 471 NBI-tracked bridges by lowest applicable component rating.
That is 13.7% of the county's reported daily bridge traffic on 11% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 4,487 crossings a day against 2,327 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 471 of 471 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
185 of the 471 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 42% 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.
LP 49 S over TURKEY CR, built 1957, carries 27,243 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 52-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 233,316 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.

What this shows Construction peaked in the 2000s, when 84 of the county's bridges still in the inventory were built, which is 17.8% of those with a recorded year. That cohort is now 15 to 24 years old in the 2024 inventory. Its average build year (1978) matches the Missouri average (1979).
The 5 Missouri counties nearest Jasper County in number of bridges, with their condition splits. Its 11% Poor share is the 6th-lowest of these 6. Its average build year of 1978 against a peer-group mean of 1980 is in line with the group.
