FHWA NBI record, refreshed with each annual release.
12TH ST in Jackson, Missouri sits above 18% of rated Missouri bridges on inventory load rating (19 t), while its 1915 build year is earlier than 98% of Jackson's recorded-year cohort (930 bridges).
12TH ST in Jackson, Missouri is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1915, 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.
