State Route 90 (SR 90) is a state highway in Southern California, United States. It consists of two unconnected pieces - the Marina Expressway and Marina Freeway near Marina del Rey and Imperial Highway in La Habra, Brea, Yorba Linda and Anaheim Hills. (The part in Yorba Linda was relinquished in 2002, and is now the Richard M. Nixon Parkway.)

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 1/4 mile (400 m) after crossing the Santa Ana River from Yorba Linda into Anaheim. Much 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".

There were once plans to connect the two sections via the Slauson Freeway and Yorba Linda Freeway, mostly parallel to Slauson Avenue, but this was never built. The full route was added to the California Freeway and Expressway System in 1959.

History

Legislative Route 221 (the Slauson Freeway, now the Marina Freeway) was defined in 1947 to run from pre-1964 Legislative Route 60 (now State Route 1) east to pre-1964 Legislative Route 165 (now Interstate 110). A 1959 extension took it east to pre-1964 Legislative Route 170 (now Interstate 605).

To the east, Legislative Route 176 (the Yorba Linda Freeway, now also the Marina Freeway) was defined in 1939 from pre-1964 Legislative Route 62 (now State Route 39) east and southeast to pre-1964 Legislative Route 43 (now State Route 91). A 1959 extension took it west to pre-1964 Legislative Route 174 (later State Route 42) near Norwalk.

In the 1964 renumbering, LR 221 was assigned State Route 90, but LR 176 all became part of State Route 42, along with the connecting LR 174 to the west. The piece of LR 176 between I-605 and SR 39 was reassigned to SR 90 in 1965, and the rest east to SR 91 became part of SR 90 in 1968 (at the same time as SR 42 became Interstate 105).

However, community opposition to additional freeway construction meant that most of the freeway sections were never completed. A short western portion to Marina Del Rey became the Richard M. Nixon Freeway, but the name was changed to the Marina Freeway after the Watergate scandal.

In 2002 the City of Yorba Linda assumed responsibility for Imperial Highway within its city limits; it lost its state route designation, and is now called the Richard M. Nixon Parkway.
