FHWA NBI record, refreshed with each annual release.
4TH ST in Ste. Genevieve, Missouri sits above 71% of rated Missouri bridges on inventory load rating (41 t), while its 1934 build year is earlier than 88% of Ste. Genevieve's recorded-year cohort (104 bridges).
4TH ST in Ste. Genevieve, Missouri is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1934, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.

No NBI category is a closure decision or a live crossing-safety verdict.
