"Spaghetti Junction" is a nickname sometimes given to a complicated or massively intertwined road traffic interchange that resembles a plate of spaghetti. The term is believed to have been coined by a journalist at the Birmingham Evening Mail in the 1970s to refer to the Gravelly Hill Interchange on the M6 motorway in Birmingham, United Kingdom. Since then many complex interchanges around the world have acquired the nickname.
