National Highway System (USA)

The National Highway System (NHS) in the United States is a network of roads that serves critical transportation needs. It includes the Interstate Highway System, which is designed for long-distance travel, as well as important roads that connect cities and communities. Established in 1995, the NHS aims to improve safety, efficiency, and access across the country. It supports economic activity by facilitating the movement of goods and people. The system is vital for national defense, emergency response, and maintaining the flow of traffic, ensuring that essential routes are prioritized for development and maintenance.
