FHWA NBI record, refreshed with each annual release.

Poor
38 t Inventory load rating Higher than 83% of rated California bridges

S GATEWAY DR in Madera, California sits above 83% of rated California bridges on inventory load rating (38 t), while its 1958 build year is earlier than 71% of Madera's recorded-year cohort (247 bridges).

S GATEWAY DR in Madera, California is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1958, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4. The lowest applicable rating sets the federal condition category, so this Poor result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.
