FHWA NBI record, refreshed with each annual release.
CALUMET AVE in Lake, Indiana sits above 15% of rated Indiana bridges on inventory load rating (26 t), while its 1992 build year is earlier than 47% of Lake's recorded-year cohort (501 bridges).
CALUMET AVE in Lake, Indiana is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1992, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.

No NBI category is a closure decision or a live crossing-safety verdict.
