 A motorway extending south from the Andersons Bay intersection was first proposed from the late 1950s, when Dunedin, like other major centres in New Zealand, was experiencing rapid vehicle growth and a decline in public transport usage.A report from De Leuw Cather was commissioned by the Dunedin City Council in 1963, which recommended a number of changes primarily to Dunedin's arterial road system.A number of roads around the city were widened to four lanes, and the report recommended that investigation, design, and construction begin of the proposed southern motorway.
