FHWA NBI record, refreshed with each annual release.

U.S. ROUTE 89 in Teton, Wyoming is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1962, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 5.

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