The Pacific Highway System is a network of highways that connects various regions along the Pacific Coast of the United States. It primarily serves as a major transportation route for both commercial and recreational travel, facilitating the movement of goods and people between states like California, Oregon, and Washington. Established in the early 20th century, the system includes several scenic routes, such as the famous Pacific Coast Highway (California State Route 1). This highway offers breathtaking views of the coastline and is popular among tourists, making it an essential part of the U.S. highway system.
