FHWA NBI record, refreshed with each annual release.
ANSONIA PL in Allegheny, Pennsylvania sits above 2% of rated Pennsylvania bridges on inventory load rating (6 t), while its 1925 build year is earlier than 90% of Allegheny's recorded-year cohort (1,294 bridges).
ANSONIA PL in Allegheny, Pennsylvania is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1925, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 3.
