Christian County, Missouri contains 121 public highway bridges.

Christian County's Poor-condition bridges carry 39,720 vehicle crossings a day

That is 5.9% of the county's reported daily bridge traffic on 7.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 4,413 crossings a day against 3,301 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 121 of 121 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

35.5% of Christian County's bridges have passed the 50-year mark

43 of the 121 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 41.3% 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 58.5% of the county's Poor-condition bridge traffic

US 65 N over FINLEY RVR, built 1960, carries 23,239 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 9-bridge count understates how much of the daily burden sits on a single crossing.
