FHWA NBI record, refreshed with each annual release.
N8/N15 in Jefferson, Nebraska sits above 14% of rated Nebraska bridges on inventory load rating (15 t), while its 1947 build year is earlier than 61% of Jefferson's recorded-year cohort (241 bridges).
N8/N15 in Jefferson, Nebraska is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1947, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 3. The lowest applicable rating sets the federal condition category, so this Poor result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.
