The Interstate System is a network of highways in the United States designed for fast and efficient travel across the country. Established in 1956, it connects major cities and regions, making it easier for people to commute, transport goods, and travel for leisure. The system is crucial for the economy, as it supports trade and commerce by allowing trucks and vehicles to move quickly between states. Each highway in the Interstate System is numbered, with odd numbers running north-south and even numbers running east-west. This organization helps drivers navigate the roads more easily. Overall, the Interstate System has transformed how Americans travel and conduct business.
