FHWA NBI record, refreshed with each annual release.
CON 1424 in Ramsey, Minnesota sits above 97% of rated Minnesota bridges on inventory load rating (52 t), while its 1964 build year is earlier than 81% of Ramsey's recorded-year cohort (341 bridges).
CON 1424 in Ramsey, Minnesota is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1964, 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.
