The Mitchell Freeway is a 41.5-kilometre-long (25.8 mi) freeway in the northern suburbs of Perth, Western Australia, linking central Perth with the city of Joondalup. It is the northern section of State Route 2, which continues south as Kwinana Freeway and Forrest Highway. Along its length are interchanges with several major roads, including the Graham Farmer Freeway and Reid Highway. The southern terminus of the Mitchell Freeway is at the Narrows Bridge, which crosses the Swan River, and the northern terminus is at Romeo Road in Alkimos.
Planning for the route began in the 1950s, and the first segment in central Perth was constructed between 1967 and 1973. Named after Sir James Mitchell, the freeway has been progressively extended north since then. In the 1970s, the first two extensions were completed, up to Hutton Street in Osborne Park. By the end of the 1980s, the freeway had reached Ocean Reef Road in Edgewater. The Yanchep line was constructed in the freeway median in the early 1990s. This necessitated the relocation of a section of the southbound carriageway, and the construction of three new bridges. In conjunction with these works, additional lanes were constructed in the realigned section.
Since the 1990s, extensions to the Mitchell Freeway have taken it to Romeo Road in Alkimos, which is the freeway's terminus as of July 2023. Further works are planned, which will eventually take the freeway past Yanchep and Two Rocks to the boundary of the Perth metropolitan region. (Full article...)
