FHWA NBI record, refreshed with each annual release.
IRR/N94 in Thurston, Nebraska sits above 19% of rated Nebraska bridges on inventory load rating (19 t), while its 1958 build year is earlier than 66% of Thurston's recorded-year cohort (152 bridges).
IRR/N94 in Thurston, Nebraska is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1958, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
