Lincoln Highway stretches 3,385 miles (5,448 kilometers) between New York City and San Francisco. It is sometimes called the Main Street of the United States. In 1912, Carl G. Fisher, an automobile manufacturer, had the idea that a coast-to-coast highway should be built. The automobile industry raised money for the highway, and construction began in 1914. After a national system of route numbers was adopted in 1926, most of what had been completed on the Lincoln Highway was designated U.S. 30.
