FHWA NBI record, refreshed with each annual release.
ROARING RIVER ROAD in Elmore, Idaho sits above 12% of rated Idaho bridges on inventory load rating (20 t), while its 1957 build year is earlier than 89% of Elmore's recorded-year cohort (97 bridges).
ROARING RIVER ROAD in Elmore, Idaho is rated Poor 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 2.

No NBI category is a closure decision or a live crossing-safety verdict.
