Clark County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Clark County ranks #19 of 75 Arkansas counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 3%). Clark County, Arkansas contains 202 public highway bridges. Roughly 43.1% are rated “Good,” 54% “Fair,” and 3% “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.

Clark County's Poor-condition bridges carry 4,951 vehicle crossings a day

That is 0.8% of the county's reported daily bridge traffic on 3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 825 crossings a day against 4,768 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.

55.4% of Clark County's bridges have passed the 50-year mark

112 of the 202 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 43.1% 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.

One structure carries 64.6% of the county's Poor-condition bridge traffic

US 67 S-5 LM 11.07 over BIG DECEIPER CREEK, built 1931, carries 3,200 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 6-bridge count understates how much of the daily burden sits on a single crossing.
