Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
US 277 in Sutton, Texas sits above 46% of rated Texas bridges on inventory load rating (27 t), while its 1957 build year is earlier than 67% of Sutton's recorded-year cohort (92 bridges).
US 277 in Sutton, Texas is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1957, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6. 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.
