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 route A10 in the metropolitan area and B10 in rural areas, and is 79 kilometres in length. This name covers many consecutive streets and is not widely known to most drivers, as the entire allocation is still best known as by the names of its constituent parts: Northcote Terrace, North East Road, Torrens Valley Road, Randell Road and Adelaide Road. This article will deal with the entire length of the corridor for sake of completion, as well to avoid confusion between declarations.
