FHWA NBI record, refreshed with each annual release.
FDR 394 in Johnson, Wyoming sits above 2% of rated Wyoming bridges on inventory load rating (10 t), while its 1989 build year is earlier than 13% of Johnson's recorded-year cohort (204 bridges).
FDR 394 in Johnson, Wyoming is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1989, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.
