FHWA NBI record, refreshed with each annual release.
K25 HWY in Logan, Kansas sits above 55% of rated Kansas bridges on inventory load rating (31 t), while its 1961 build year is earlier than 45% of Logan's recorded-year cohort (55 bridges).
K25 HWY in Logan, Kansas is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1961, 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.
