List of Highways in US: Type of Highways

Below are the types of highways:

Interstate Highways	The Interstate Highway System, established in 1956 under the Federal-Aid Highway Act, is the primary network of controlled-access highways in the United States. These highways are crucial for long-distance travel, connecting major cities and regions. The Interstate Highways are identified by a unique numbering system, which signifies their direction and location. For example, even-numbered highways generally run east-west, while odd-numbered highways typically run north-south.
U.S. Routes	U.S. Routes are a major component of the U.S. highway system and were established in 1926. These highways connect cities, towns, and regions, serving as important conduits for both interstate and intrastate travel. U.S. Routes have a distinctive shield design and are an integral part of the country’s transportation infrastructure. They often complement the Interstate Highways, providing alternative routes and connecting smaller communities.
State Highways	Each state has its own system of state highways, which are essential for intrastate travel and connectivity. These roads vary in size and importance, serving as critical links between local communities and contributing to regional development. State highways play a vital role in transporting goods and people within a specific state, addressing the unique transportation needs of each region.
Scenic Byways	Scenic Byways are designated routes that showcase the natural beauty, cultural heritage, and historical significance of specific regions. These highways offer travelers a more leisurely and picturesque journey, encouraging exploration and appreciation of the country’s diverse landscapes. The All-American Road and National Scenic Byway programs recognize and promote these routes, highlighting their importance in preserving America’s scenic and cultural treasures.

List of Highways in US: The Numbering System

Understanding the numbering system is crucial for navigating the vast U.S. highway system. Both Interstate Highways and U.S. Routes follow a specific convention that provides valuable information about each highway.

Interstate Highway Numbering

The numbering of Interstate Highways is systematic and provides information about the highway’s location and orientation. Odd-numbered highways (e.g., I-5, I-95) typically run north-south, with lower numbers in the west and higher numbers in the east. Even-numbered highways (e.g., I-10, I-40) usually run east-west, with lower numbers in the south and higher numbers in the north. Three-digit Interstate numbers signify auxiliary routes, loops, or spurs connected to a main route.

U.S. Route Numbering

U.S. Route numbers also follow a specific pattern. Even-numbered routes generally run east-west, with the lowest numbers in the north and the highest in the south. Odd-numbered routes typically run north-south, with the lowest numbers in the west and the highest in the east. Like the Interstate system, three-digit U.S. Route numbers indicate auxiliary routes, connectors, or alternate routes.
