Good
51 t Inventory load rating Higher than 96% of rated Minnesota bridges

CON 1248 in St. Louis, Minnesota sits above 96% of rated Minnesota bridges on inventory load rating (51 t), while its 1983 build year is earlier than 58% of St. Louis's recorded-year cohort (663 bridges).

CON 1248 in St. Louis, Minnesota is rated Good in the FHWA's 2024 National Bridge Inventory. Built in 1983, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 7.

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