FHWA NBI record, refreshed with each annual release.
MERIDIAN RD in Marion, Oregon sits above 39% of rated Oregon bridges on inventory load rating (26 t), while its 1954 build year is earlier than 82% of Marion's recorded-year cohort (373 bridges).
MERIDIAN RD in Marion, Oregon is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1954, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 2.
