CR257 in Jefferson, Florida sits above 90% of rated Florida bridges on inventory load rating (54 t), while its 1984 build year is earlier than 27% of Jefferson's recorded-year cohort (70 bridges).
CR257 in Jefferson, Florida is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1984, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
