FHWA NBI record, refreshed with each annual release.
SR4007 in Butler, Pennsylvania sits above 5% of rated Pennsylvania bridges on inventory load rating (16 t), while its 1969 build year is earlier than 53% of Butler's recorded-year cohort (378 bridges).
SR4007 in Butler, Pennsylvania is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1969, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.

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