 Its original alignment, which was gazetted in 1949 as Road No.10578 by the Wanneroo Road Board, was a straight east-west road extending to Alexander Drive, but in the mid-1970s, the alignment was altered southwards in the vicinity of the freeway alignment (the Mitchell Freeway was not, however, built until 1986), and in the late 1970s, the section east of Wanneroo Road was split off to form Marangaroo Drive.Apart from the Glengarry and Greenwood neighbourhood shopping centres, Warwick Road also passes Warwick Open Space east of Erindale Road and the Percy Doyle Reserve, which includes sports and recreation facilities and the Duncraig Library, near Marmion Avenue.
