Interstate 10 originates from California State Route 1 (Pacific Coast Highway), just off the shore of the Pacific Ocean at Santa Monica. Within the Golden State, I-10 is a vital east-west freeway across the Los Angeles Basin. It connects the Inland Empire with the area around Palm Springs, then continues due east toward Blythe and Phoenix, Arizona. It replaced U.S. 60-70 through California.
