FHWA NBI record, refreshed with each annual release.
SH 222 in Knox, Texas sits above 3% of rated Texas bridges on inventory load rating (23 t), while its 1960 build year is earlier than 47% of Knox's recorded-year cohort (51 bridges).
SH 222 in Knox, Texas is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1960, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 3. The lowest applicable rating sets the federal condition category, so this Poor 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.
