State Route 90 (SR 90) is a state highway in Southern California, United States. It consists of two unconnected pieces in Greater Los Angeles. The Marina Freeway segment is a short freeway in southwestern Los Angeles and the nearby suburbs, linking Marina del Rey to the rest of Greater Los Angeles. The limited-access portion runs from Slauson Avenue in southern Culver City to just past Culver Boulevard, where it forms the approximate border between the Del Rey and Westchester neighborhoods of the city of Los Angeles. The route continues westward into unincorporated Marina del Rey as an expressway, terminating at Lincoln Boulevard. The eastern portion of Route 90 is Imperial Highway connecting La Habra, Brea, Yorba Linda and Anaheim Hills. The part in Yorba Linda was relinquished in 2002, and the portion built to freeway standards is now known by two names: The Richard M. Nixon Parkway between Yorba Linda Blvd. and Kellogg Drive, and the Richard M. Nixon Freeway between Kellogg Drive and its southern terminus at Orangethorpe Avenue.
