California State Routes are a network of highways and roads that facilitate travel throughout the state of California. These routes are designated by the California Department of Transportation (Caltrans) and are marked with a distinctive shield sign. They connect major cities, towns, and attractions, making it easier for residents and visitors to navigate the diverse landscapes of the state. The state routes vary in size and importance, ranging from busy urban thoroughfares to scenic byways. Some notable routes include State Route 1, which runs along the stunning Pacific Coast, and State Route 101, a major north-south corridor. These routes play a crucial role in California's transportation system.
