State Route 90 (SR 90) is a state highway in the U.S. state of California that consists of two unconnected pieces in Greater Los Angeles. Most of the western portion of SR 90 is the Marina Freeway, a short freeway in southwestern Los Angeles and the nearby suburbs, linking Marina del Rey to the rest of Greater Los Angeles. SR 90 begins at Lincoln Boulevard (State Route 1) near Marina del Rey as the Marina Expressway. It then goes past a few intersections before becoming the Marina Freeway. It then continues eastward approximately along the border between the Del Rey and Westchester neighborhoods of the city of Los Angeles before terminating in Slauson Avenue in southern Culver City to just past Culver Boulevard. The eastern portion of SR 90 runs along Imperial Highway between Beach Boulevard (State Route 39) in La Habra and State Route 91 in Anaheim Hills, also passing through Brea and Yorba Linda. A stretch in Yorba Linda between Yorba Linda Boulevard and Orangethorpe Avenue was relinquished to the city in 2002 and built to freeway standards. The city renamed it the Richard M. Nixon Freeway in honor of the 37th President of the United States, Richard Nixon, who was born in Yorba Linda less than half a mile away from the road. Route description The west segment of SR 90 begins at Lincoln Boulevard (State Route 1) in the Del Rey district of Los Angeles. It heads east along the Marina Expressway, past several intersections, and becomes the Marina Freeway after crossing Ballona Creek. After two interchanges - with Centinela Avenue and Interstate 405 - SR 90 and the freeway end at Slauson Avenue. The east segment begins at the intersection of Imperial Highway and Beach Boulevard (State Route 39) in La Habra. It heads east and southeast on Imperial Highway, ending at State Route 91 about after crossing the Santa Ana River from Yorba Linda into Anaheim. A portion of the road in Yorba Linda is built to freeway standards; it is now known as the Richard M. Nixon Parkway after the city accepted maintenance in 2002. However, the same state law that authorized relinquishment required the city to "maintain signs directing motorists to the continuation of Route 90". SR 90 is part of the California Freeway and Expressway System, and is part of the National Highway System, a network of highways that are considered
