Before the completion of the North-South Motorway (M2), part of which was also known as the South Road Superway in Adelaide's northern suburbs, the introduction of A2 between Adelaide's northern suburbs and Bedford Park, plus the extension of A9 between Wingfield and Elizabeth Vale, A13 was made up of John Rice Avenue, Salisbury Highway, South Road, Main South Road, Victor Harbor Road, Adelaide Road, Hindmarsh Road and Torrens Street.
One of the main north-south routes through metropolitan Adelaide and to the Fleurieu Peninsula, the route started in the northern suburb of Elizabeth Vale, then headed southwest along John Rice Avenue to Salisbury then as the Salisbury Highway over the interchange with Port Wakefield Road at Greenfields to the interchange with the Port River Expressway (A9). Turning south, the road followed South Road through the northwest, western and southwestern suburbs to Darlington and then as Main South Road through Morphett Vale, Reynella and Old Noarlunga. From Old Noarlunga, Main South Road continues south as B23, while A13 follows Victor Harbor Road to the small town of Mount Compass then south onto the holiday destination of Victor Harbor. 2
