National Bridge Inventory

The National Bridge Inventory (NBI) is a comprehensive database maintained by the Federal Highway Administration in the United States. It contains detailed information about thousands of bridges nationwide, including their location, structural condition, and design type. The NBI helps transportation agencies assess bridge safety, prioritize maintenance, and allocate funding for repairs or replacements. Regular inspections ensure that the data is updated, providing crucial insights for infrastructure planning and safety management, ultimately helping to prevent bridge failures and enhance public safety.
