CR 750S in Boone, Indiana sits above 28% of rated Indiana bridges on inventory load rating (31 t), while its 1964 build year is earlier than 67% of Boone's recorded-year cohort (293 bridges).
CR 750S in Boone, Indiana is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1964, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.
