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

State Route 42 was a state highway in southern region of the U.S. State of California, running along Manchester Avenue, Manchester Boulevard and Firestone Boulevard in Los Angeles and the cities south of it. After 1968, it ran from State Route 1 west of Inglewood east to Interstate 5 in Norwalk...

, its name was changed to the current appellation.

From the I-405 Freeway west to Centinela Avenue, the Marina Freeway is 8 lanes wide, before it quickly narrows to 4 lanes at the Culver Boulevard exit. The freeway ends approximately 1/2 mile west of Culver Boulevard, and continues as an expressway. There has been talk of extending the Marina Expressway slightly west of Lincoln Boulevard (Route 1) to Admiralty Way (approximately 1/4 mile) to accommodate ongoing expansion of the Marina Del Rey area. Strong opposition to this makes actualization of this plan uncertain.

In 2002 the City of Yorba Linda assumed responsibility for Imperial Highway

 within its city limits due to AB 887; it lost its state route designation, and is now called the Richard M. Nixon Parkway.

By 2005, construction on the western end of the Marina Freeway began, to extend the freeway terminus from Culver Boulevard to approximately 1/2 mile west of Culver Boulevard by building a full interchange at Culver. The freeway extension was completed in early 2007. The freeway extension also allows Route 90 drivers to avoid a traffic signal at Alla Road (just west of Culver Boulevard.). After the end of the freeway, a pair of frontage roads operating as an expressway continues as Route 90 up to Route 1 (Lincoln Boulevard). Signalized intersections occur at Mindanao Way and Lincoln Boulevard, which is the end of the expressway in Marina del Rey. The reason for the extension is to relieve traffic congestion on surface streets.
