Adelaide–Mannum Road is a road that runs through the northern Adelaide Hills between the South Australian capital, Adelaide and Mannum on the Murray River. It is designated State Highway A10 in the metropolitan area and B10 in rural areas, and is 77 kilometres in length. It is named after the two centres that it links. The 22 km stretch from Houghton to Adelaide is known as North East Road.
North East Road
North East Road is a major arterial road that travels, as its name suggests, through the north-eastern suburbs of the Australian city of Adelaide. It starts (as Northcote Terrace) at the intersection of Robe Terrace and Park Road/Mann Road in North Adelaide, about 500 metres away from the beginning of Adelaide's O-Bahn Busway, travelling through Adelaide's north-east growth corridor, beyond it to the distinctly less-urban region of Houghton, where it meets in an intersection with the Lower North East Road, leading back to Adelaide's more easterly suburbs.
The road passes through Modbury and the district's shopping centre, the Westfield Tea Tree Plaza, and the terminus of the O-Bahn at the Tea Tree Plaza Interchange just outside it. It intersects with Hampstead Road/Ascot Avenue in Vale Park, and also with the Grand Junction Road in Valley View.
The road was first built in the 1840s to facilitate the growth and development of the towns and settlements along its length. It played a role in the gold rush of the 1860s. Today, the area boasts many tourist and historical sites, wineries and natural attractions, although only a few towns exist as more than historical sites.
