Armadale Road is a major road in the south and south east of the Perth Metropolitan Area. It serves three purposes: firstly, providing a main route from Armadale to Fremantle; secondly, connecting Armadale to the Kwinana Freeway; and thirdly, since 2005, connecting it to the Tonkin Highway which ferries traffic to the eastern suburbs, Perth Airport and the Forrestfield and Kewdale industrial areas.

The major junction of the South Western and Albany Highways, which connect Perth with the South West and Great Southern regions of Western Australia respectively, is located within the suburb.
