The Central Motorway Junction or CMJ (best known as Spaghetti Junction and rarely as Central Motorway Intersection), is the intersection of New Zealand State Highways 1 and 16, just south of the central business district of Auckland, New Zealand. A multilevel structure (at least three traffic lanes crossing above each other in several locations), it has been described as a "fiendishly complicated, multi-layered puzzle of concrete, steel and asphalt". Carrying around 200,000 vehicles a day, it is one of the busiest stretches of road in New Zealand.
