Beginning with animal migration paths, followed by Native American trails, wagon roads, and today's superhighways, the Golden State's system of roads has been shaped by its varied physical terrain. At the same time, California's thousands of miles of roads have both helped to define the state and connect it to the greater world.
For example, where water has presented barriers to travel, Californians have overcome them with a system of ferries and later a network of 24,000 bridges. All these networks continue to remain works in progress as Californians face the challenge of getting from one place to another. With 175,000 miles of roads throughout the state, 35 million registered vehicles and 330 million miles traveled in 2010, California's roads are now faced with even greater challenges since the first automobile arrived here in 1898.
