FHWA NBI record, refreshed with each annual release.
ONE ST in York, Maine sits above 57% of rated Maine bridges on inventory load rating (39 t), while its 1938 build year is earlier than 88% of York's recorded-year cohort (236 bridges).
ONE ST in York, Maine is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1938, 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.
