K39 HWY in Bourbon, Kansas sits above 60% of rated Kansas bridges on inventory load rating (33 t), while its 1933 build year is earlier than 75% of Bourbon's recorded-year cohort (206 bridges).
K39 HWY in Bourbon, Kansas is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1933, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
