Poor
22 t Inventory load rating Lower than 78% of rated Idaho bridges

FOREST ROAD 651 in Idaho, Idaho sits above 22% of rated Idaho bridges on inventory load rating (22 t), while its 1956 build year is earlier than 83% of Idaho's recorded-year cohort (215 bridges).

FOREST ROAD 651 in Idaho, Idaho is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1956, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 2. 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.
