Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
PLANT ROAD K in Des Moines, Iowa sits above 4% of rated Iowa bridges on inventory load rating (7 t), while its 1905 build year is earlier than 97% of Des Moines's recorded-year cohort (176 bridges).
PLANT ROAD K in Des Moines, Iowa is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1905, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 5. 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.
