Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
CH 12 in Kankakee, Illinois sits above 19% of rated Illinois bridges on inventory load rating (29 t), while its 1979 build year is earlier than 57% of Kankakee's recorded-year cohort (344 bridges).
CH 12 in Kankakee, Illinois is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1979, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4. The lowest applicable rating sets the federal condition category, so this Poor result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.
