The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Sheridan County pairs a top-5% lowest Poor-condition share among rated counties in the state with an older average build year than the state 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, Sheridan County ranks #4 of 88 Nebraska counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 0%). Sheridan County, Nebraska contains 63 public highway bridges. Roughly 85.7% are rated “Good,” 14.3% “Fair,” and 0% “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.

Share of 63 NBI-tracked bridges by lowest applicable component rating.
36 of the 63 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 85.7% 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.
