U.S. Interstate Highway System
The U.S. Interstate Highway System is a network of highways that spans across the United States, designed to facilitate efficient transportation. Established in 1956, it connects major cities and regions, promoting trade and travel. The system includes over 47,000 miles of roads, which are numbered for easy navigation.
Interstate highways are built to high standards, allowing for faster travel and safer driving conditions. They often feature multiple lanes, limited access points, and are maintained by both federal and state governments. This system plays a crucial role in the economy and daily life of Americans.
