In what year were the National Bridge Inspection Standards (NBIS) established?

• A. 1965
• B. 1980
• C. 1971
• D. 1995

Answer: (C)

NBIS established a nationwide, standardized approach to inspecting and rating bridges on public roads. This program introduced formal requirements for how often bridges must be inspected, who is qualified to perform the inspections, and how findings are documented using a common rating system to identify deficiencies and prioritize repairs. The year 1971 marks the formal creation of this nationwide framework, setting the baseline for how bridge safety data is collected and used across all states. The other years correspond to different stages or updates in highway programs, not the initial establishment of NBIS.
