Cedar County Bridge Snapshot

Cedar County, Missouri contains 112 public highway bridges. Roughly 24.1% are rated “Good,” 50.9% “Fair,” and 25% “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.

Cedar County's Poor-condition bridges carry 7,383 vehicle crossings a day

That is 13% of the county's reported daily bridge traffic on 25% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 264 crossings a day against 531 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.

56.3% of Cedar County's bridges have passed the 50-year mark

63 of the 112 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 24.1% 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.

One structure carries 14.6% of the county's Poor-condition bridge traffic

RT J S over SAC RVR, built 1967, carries 1,081 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 28-bridge count understates how much of the daily burden sits on a single crossing.
