FHWA NBI record, refreshed with each annual release.
Venetian Causeway in Miami-Dade, Florida sits above 1% of rated Florida bridges on inventory load rating (4 t), while its 1927 build year is earlier than 98% of Miami-Dade's recorded-year cohort (1,057 bridges).
Venetian Causeway in Miami-Dade, Florida is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1927, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
