FHWA NBI record, refreshed with each annual release.
SR 137 WB (TULARE) in Tulare, California sits above 87% of rated California bridges on inventory load rating (41 t), while its 1952 build year is earlier than 53% of Tulare's recorded-year cohort (589 bridges).
SR 137 WB (TULARE) in Tulare, California is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1952, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.

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