County profile · official public datasets
274 public highway bridges tracked in the FHWA National Bridge Inventory: 43.1% rated Good, 43.1% Fair, 13.9% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Cass County posts a higher-than-median Poor-condition share among rated counties in the state across mid-size county bridge inventory.
Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Cass County ranks #76 of 88 Nebraska counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 13.9%). Cass County, Nebraska contains 274 public highway bridges. Roughly 43.1% are rated “Good,” 43.1% “Fair,” and 13.9% “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.

Share of 274 NBI-tracked bridges by lowest applicable component rating.
That is 1.7% of the county's reported daily bridge traffic on 13.9% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 451 crossings a day against 7,151 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 274 of 274 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
96 of the 274 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.
Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.
N50 over BNSF RR 073-015-R, built 1957, carries 6,570 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 38-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 17,135 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
