By Shumaila Saeed || Published on January 19, 2024
Interstate refers to a network of highways connecting multiple states, primarily for long-distance travel; highways are major public roads, often including Interstates, state, and local roads.
Key Differences
Interstate highways form a network across the United States, linking multiple states with controlled access for efficient long-distance travel. Highways, in general, encompass a broader category of major roads that can include Interstates, state roads, and local routes.

Designed primarily for high-speed, long-distance travel, Interstates have minimal access points to ensure smooth traffic flow. Highways, on the other hand, vary widely in their design, ranging from small rural roads to large urban freeways, including parts of the Interstate system.
