FHWA NBI record, refreshed with each annual release.
SEACREST BLVD. in Palm Beach, Florida sits above 79% of rated Florida bridges on inventory load rating (46 t), while its 1959 build year is earlier than 90% of Palm Beach's recorded-year cohort (610 bridges).
SEACREST BLVD. in Palm Beach, Florida is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1959, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 5. 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.
