FHWA NBI record, refreshed with each annual release.
12TH ST NB in McLennan, Texas sits above 43% of rated Texas bridges on inventory load rating (25 t), while its 1958 build year is earlier than 76% of McLennan's recorded-year cohort (714 bridges).
12TH ST NB in McLennan, Texas is rated Fair 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 6.
