Interstate 10 and California 1 trailblazers posted along Colorado Avenue between Sixth Street and Seventh Street in Santa Monica. Seventh Street leads to California 1 north; Lincoln Boulevard (old U.S. 66) connects with I-10 east and California 1 south. Photo taken 10/30/05.

Interstate 10 originates from California 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.
