National Bridge and Tunnel Inventory and Inspection Standards

Purpose

To protect the safety of the traveling public and support the movement of people and goods on which the economy relies, there are Federal requirements for the inventory and inspection of bridges and tunnels on all public roads and the standards used for the inventory and inspections. This provides a basis for a data-driven, risk-based approach to, and cost-effective strategy for, bridge and tunnel investment.
