S MIAMI AV - I-95N in Miami-Dade, Florida is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1968, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.

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