FHWA NBI record, refreshed with each annual release.
RANGE LINE in Miami, Ohio sits above 26% of rated Ohio bridges on inventory load rating (32 t), while its 1973 build year is earlier than 59% of Miami's recorded-year cohort (315 bridges).
RANGE LINE in Miami, Ohio is rated Good in the FHWA's 2024 National Bridge Inventory. Built in 1973, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 7.
