national highways
Cross-country arterial routes
National highways are major roads maintained by a country's central government, forming the primary network connecting cities, states, and regions.
They're distinguished from local roads or state highways by their national importance and federal funding: The national highway system spans over 160,000 miles.
In the United States, the Interstate Highway System is the most prominent example.
