CR 600E in Porter, Indiana sits above 16% of rated Indiana bridges on inventory load rating (27 t), while its 1971 build year is earlier than 42% of Porter's recorded-year cohort (277 bridges).
CR 600E in Porter, Indiana is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1971, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
