Route 66, also known as the "Main Street of America," is a historic highway that was one of the original highways in the U.S. highway system. The Route 66 End of the Trail is the western terminus of the highway and is located in Santa Monica, California.

The highway spans over 2,400 miles and stretches from Chicago, Illinois to Santa Monica, California. It was an important highway for travelers and truckers, providing a direct route from the Midwest to the West Coast.
