Carrying SR 4 over JAMES WOLF CREEK
7.5 MI E I 55, Tate, Mississippi
Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
SR 4 in Tate, Mississippi is rated Fair in the FHWA's 2024 National Bridge Inventory.
Built in 1974, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 5. The lowest applicable rating sets the federal condition category, so this Fair result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.
