NBIS requires that inspections be conducted within what timeframe after opening to traffic?

Explanation:
When a bridge first opens to traffic, an initial inspection must be completed within 12 months to establish a baseline condition. This early check catches any construction or early-service issues and provides a reference point for tracking changes over time. After this baseline, routine NBIS inspections follow a two-year cycle, conducted at least every 24 months. So, the 12-month timeframe is the correct window for the first inspection, with 24 months later being the regular cadence. The other timeframes don’t fit the established sequence for the initial versus ongoing inspections.
