FHWA NBI record, refreshed with each annual release.
183RD ST in Johnson, Kansas is rated Fair in the FHWA's 2024 National Bridge Inventory.
Built in 1967, 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.
