FHWA NBI record, refreshed with each annual release.
CTH RC in Richland, Wisconsin sits above 7% of rated Wisconsin bridges on inventory load rating (21 t), while its 1970 build year is earlier than 81% of Richland's recorded-year cohort (298 bridges).
CTH RC in Richland, Wisconsin is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1970, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
