FHWA NBI record, refreshed with each annual release.
OR 140 (HWY 020) in Klamath, Oregon sits above 1% of rated Oregon bridges on inventory load rating (7 t), while its 1957 build year is earlier than 92% of Klamath's recorded-year cohort (248 bridges).
OR 140 (HWY 020) in Klamath, Oregon is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1957, 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.
