Mingo County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Mingo County ranks #21 of 55 West Virginia counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 15.2%). Mingo County, West Virginia contains 165 public highway bridges. Roughly 29.1% are rated “Good,” 55.8% “Fair,” and 15.2% “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.

Mingo County's Poor-condition bridges carry 32,970 vehicle crossings a day

That is 13.9% of the county's reported daily bridge traffic on 15.2% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,319 crossings a day against 707 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 165 of 165 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

13.9% of Mingo County's bridges have passed the 50-year mark

23 of the 165 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 29.1% 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 20.3% of the county's Poor-condition bridge traffic

US 119 over CSX RAILROAD, built 1970, carries 6,700 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 25-bridge count understates how much of the daily burden sits on a single crossing.
