Patterson Road

Patterson Road is a major road between Kwinana and Rockingham and is part of Australia's National Route 1 for part of its length.^[1] The first part goes through Kwinana's heavy industrial area. After the Ennis Avenue turnoff which takes Highway 1 with it, Patterson Road becomes State Route 18^[1] and goes through the Rockingham Beach area until it turns into Railway Terrace one block from the ocean at Mangles Bay, which is part of the Indian Ocean.
