FHWA NBI record, refreshed with each annual release.
AVE 25 in Madera, California sits above 24% of rated California bridges on inventory load rating (26 t), while its 1954 build year is earlier than 83% of Madera's recorded-year cohort (247 bridges).
AVE 25 in Madera, California is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1954, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 2.
