New Zealand State Highway 85

State Highway 85 is a South Island State Highway in New Zealand, servicing the Maniototo Plains and the North and Central Otago regions of the South Island between the major settlements of Alexandra and Palmerston. It is wholly two lane and passes through some of the most extreme climatic regions in New Zealand. The highway is known colloquially as "The Pigroot". Though there is no definitive explanation for this name, A. W. Reed, in his book Place Names of New Zealand, mentions an incident during John Turnbull Thomson's survey of inland Otago in which local wild pigs were so unafraid of humans that a huge boar approached his party and rubbed its nose against that of Thomson's horse.
