Dakota County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Dakota County ranks #66 of 88 Nebraska counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 9.6%). Dakota County, Nebraska contains 73 public highway bridges. Roughly 50.7% are rated “Good,” 39.7% “Fair,” and 9.6% “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.

Dakota County's Poor-condition bridges carry 595 vehicle crossings a day

That is 0.2% of the county's reported daily bridge traffic on 9.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 85 crossings a day against 3,841 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.

35.6% of Dakota County's bridges have passed the 50-year mark

26 of the 73 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 50.7% 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 68.9% of the county's Poor-condition bridge traffic

JOHN ST/FAS 3940 over OMAHA CREEK, built 1984, carries 410 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 7-bridge count understates how much of the daily burden sits on a single crossing.
