Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
NC24W in Onslow, North Carolina sits above 17% of rated North Carolina bridges on inventory load rating (29 t), while its 1942 build year is earlier than 98% of Onslow's recorded-year cohort (172 bridges).
NC24W in Onslow, North Carolina is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1942, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.

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