FHWA NBI record, refreshed with each annual release.
LA0300 in St. Bernard, Louisiana sits above 21% of rated Louisiana bridges on inventory load rating (22 t), while its 1957 build year is earlier than 96% of St. Bernard's recorded-year cohort (47 bridges).
LA0300 in St. Bernard, Louisiana is rated Fair 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 6. The lowest applicable rating sets the federal condition category, so this Fair 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.
