Description
The National Highway System (NHS) is a network of nationally significant highways selected by the state and Metropolitan Planning Organizations and approved by Congress to ensure continuity across state lines and connection with other priority transportation networks. It includes the Interstate System, Strategic Defense Highway System, other principal arterials, and connectors to major intermodal terminals. The roadways are color-coded according to subcategories of the NHS and also depict all other non-NHS arterials and collectors for reference.
