What is the National Bridge Inventory (NBI)?

• A. A Maintenance Scheduling System
• B. A List of All Bridges by Location
• C. The Aggregation of Structure Inventory and Appraisal Data Collected by Each State to Fulfill NBIS
• D. A Tool for Toll Collection

Answer: (C)

The National Bridge Inventory is the aggregation of structure inventory and appraisal data collected by each State to fulfill the National Bridge Inspection Standards. In practice, state transportation agencies gather data about each bridge—its location, attributes, condition ratings, and inspection results—and submit it into the NBI so that federal and state agencies can monitor bridge safety, plan repairs, and track nationwide trends. It’s not a maintenance scheduling system, nor simply a list of bridges by location, nor a toll collection tool.
