California freeways are an extensive network of highways designed to facilitate fast and efficient travel across the state. They are known for their multi-lane configurations, allowing for high-speed traffic flow. Major routes include the Interstate 5, Interstate 10, and U.S. Route 101, connecting key cities like Los Angeles, San Francisco, and San Diego. These freeways often feature scenic views, especially in coastal areas, and are equipped with various amenities such as rest stops and gas stations. Traffic congestion can be common, particularly during peak hours, making real-time navigation tools essential for drivers.
