Residential build-out in Avalon was mostly completed by the late 1960s, however some additional residential development occurred south of Glasgow Street and west of Clarence Avenue in the mid-1990s, along with some limited remnant development west of Melrose Avenue in the 1980s. As noted below, plans for the southwest extension of Circle Drive initially caused some concern; construction of an interchange at Clarence Avenue and Circle, in the planning since the 1960s, was completed by the late 2000s, facilitating resident access to the freeway and to the Stonebridge commercial area to the southeast.
