FHWA NBI record, refreshed with each annual release.
U.S. 281 in Caddo, Oklahoma sits above 8% of rated Oklahoma bridges on inventory load rating (16 t), while its 1933 build year is earlier than 94% of Caddo's recorded-year cohort (424 bridges).
U.S. 281 in Caddo, Oklahoma is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1933, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4. The lowest applicable rating sets the federal condition category, so this Poor 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.
