The Salisbury Highway (part of Route A9, previously Route A13 / National Highway A13) is a 12 kilometre major connecting road in the northern suburbs of the Adelaide metropolitan area.
Salisbury Highway is dual carriageway in its entirety. It starts as Route A9 (formerly A13 until May 2017) in Elizabeth Vale as John Rice Avenue. Past the suburb of Salisbury it takes on its Salisbury Highway name. It then runs parallel to Main North Road (Route A20) and crosses over Kings Road (Route A18). At Port Wakefield Road (National Highway A1), it previously changed status to National Highway A13 (now A9 right through) before ending at the intersection of the Port River Expressway and South Road. Route A9 continues along Port River Expressway. Prior to 2017, National Highway A13 then followed South Road to Grand Junction Road (Route A16 / National Highway A16), where it changed status back to Route A13 and continued south along South Road, Main South Road and Victor Harbor Road, terminating at Victor Harbor on the south coast. The South Road Superway is designated Route M2, and South Road continuing from it was converted to route A2 in May 2017. The renumbering occurred during construction of the Northern Connector which continues north from South Road.
Until the early 1990s, Salisbury Highway terminated at Port Wakefield Road. The Salisbury Highway Extension project built the bridge and interchange at Port Wakefield Road, and extended the highway to Wingfield, where it joined the north end of what was then the South Road Interconnector. Neither the Port River Expressway nor the elevated South Road Superway had been built at that time.
