Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
OSHIRO RD in Hawaii, Hawaii sits above 53% of rated Hawaii bridges on inventory load rating (31 t), while its 1940 build year is earlier than 64% of Hawaii's recorded-year cohort (237 bridges).
OSHIRO RD in Hawaii, Hawaii is rated Good in the FHWA's 2024 National Bridge Inventory. Built in 1940, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 7. The lowest applicable rating sets the federal condition category, so this Good 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.
