Fair
37 t Inventory load rating Higher than 80% of rated Nebraska bridges

N47 in Dawson, Nebraska sits above 80% of rated Nebraska bridges on inventory load rating (37 t), while its 1971 build year is earlier than 54% of Dawson's recorded-year cohort (300 bridges).

N47 in Dawson, Nebraska is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1971, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6. The lowest applicable rating sets the federal condition category, so this Fair 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.
