CH 17(FAS 529) in Champaign, Illinois is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1963, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 3.

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