FHWA NBI record, refreshed with each annual release.
RTE 66 in Columbia, New York sits above 19% of rated New York bridges on inventory load rating (29 t), while its 1886 build year is earlier than 100% of Columbia's recorded-year cohort (243 bridges).
RTE 66 in Columbia, New York is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1886, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 5.

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