National Highway System

The National Highway System (NHS) is a network of important roads in the United States designed to facilitate efficient transportation and commerce. Established in the 1990s, the NHS includes interstates, major highways, and other vital routes that connect cities and regions. This system is crucial for economic activities, emergency response, and public safety, ensuring that goods and people can move effectively across the country. The NHS is maintained by federal, state, and local governments, reflecting a coordinated effort to enhance the nation’s infrastructure.
