Clark County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Clark County ranks #107 of 120 Kentucky counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 12%). Clark County, Kentucky contains 117 public highway bridges. Roughly 27.4% are rated “Good,” 60.7% “Fair,” and 12% “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. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

Clark County's Poor-condition bridges carry 12,611 vehicle crossings a day

That is 2.8% of the county's reported daily bridge traffic on 12% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 901 crossings a day against 2,094 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 117 of 117 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

47% of Clark County's bridges have passed the 50-year mark

55 of the 117 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 27.4% 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 49.1% of the county's Poor-condition bridge traffic

US-60 over I-64, built 1959, carries 6,197 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 14-bridge count understates how much of the daily burden sits on a single crossing.
