The Strategic Highway Network (STRAHNET) is a system of public highways that are a key part of the deployment of the United States Armed Forces. It provides defense access, continuity, and emergency capabilities for movements of personnel and equipment in both peacetime and war to support U.S. military operations.  Routes are assigned to STRAHNET through a collaborative effort from the U.S. Department of Defense, the Federal Highway Administration (FHWA), state transportation departments, military services and installations, and ports.  

The FHWA Highway Performance Monitoring System (HPMS) report, which ADOT is required to submit every year, includes an item that identifies two types of STRAHNET routes:  

• Regular STRAHNET Routes (code 1) are those identified as the primary routes needed for national defense

• Connectors (code 2) are additional routes that provide the most direct and highest functional class route to link military installations and ports to a regular STRAHNET route  

Together, STRAHNET and the connectors define the total minimum public highway network needed to support a defense emergency.  Note that all STRAHNET routes and connectors are included in the National Highway System (NHS).
