FHWA NBI record, refreshed with each annual release.
I-80 (SR-80) WBL in Summit, Utah sits above 40% of rated Utah bridges on inventory load rating (31 t), while its 1971 build year is earlier than 59% of Summit's recorded-year cohort (138 bridges).
I-80 (SR-80) WBL in Summit, Utah is rated Fair 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 5.

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