In 1921 a westward expansion of Sunset began, extending the road from the then-current terminus at Sullivan Canyon toward the coast. This land, a portion of the original 1838 holdings of Francisco Marquez, stretched across a mesa and became known as the "Riviera section". Will Rogers, who had bought much of this land as an investment, later donated it to the State of California creating Will Rogers State Historic Park. Circa 1931, Sunset was a paved road from Horn Avenue to Havenhurst Avenue.
