FHWA NBI record, refreshed with each annual release.
SR1511 in Caldwell, North Carolina sits above 70% of rated North Carolina bridges on inventory load rating (50 t), while its 1998 build year is earlier than 26% of Caldwell's recorded-year cohort (201 bridges).
SR1511 in Caldwell, North Carolina is rated Good in the FHWA's 2024 National Bridge Inventory. Built in 1998, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 7.
