Route 66: The Mother Road.
Route 66 is a historic highway that runs 2,448 miles (3,937 km) from Chicago, Illinois, to Santa Monica, California.
It was one of the first highways in the United States and was a major route for travelers and commerce for decades.
Route 66 was designated as a federal highway in 1926. It quickly became a popular route for travelers, who enjoyed the open road and the opportunity to see the American West. Route 66 was also a major route for commerce, and many businesses sprang up along the highway to serve travelers.
Route 66 reached its peak in the 1950s, when it was the main route for travelers between the Midwest and the West Coast. However, the construction of the Interstate Highway System in the 1960s led to the decline of Route 66.
The interstate highways were faster and more direct than Route 66, and many businesses along the highway closed.
