TANANA BRIDGE ROAD
Carrying TANANA BRIDGE ROAD over BOUNDRY SLOUGH
1.0 KM W-SW TANANA R BR, Fairbanks North Star, Alaska
Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
TANANA BRIDGE ROAD in Fairbanks North Star, Alaska is rated Fair in the FHWA's 2024 National Bridge Inventory.
Built in 2012, 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.
