Understand the Impacts (Step 6) 91 On a smaller scale, but no less important to those affected, the loss of service for a critical bridge on a busy highway bypass, which might arise from an unexpected finding in a routine structural inspection, could cause massive disruption along the surface streets of the community served by the bypass as well as to the people and goods that attempt to move through the area.

94 Mainstreaming System Resilience Concepts into Transportation Agencies: A Guide Factor 6.3: Have you identified interdependencies with other networks that interface with your system? To be a truly resilient transportation system, it is important to identify how the assets in your system depend on other infrastructure and how these interdependencies may affect asset operation during various hazards/threats.
