Spaghetti junction
Spaghetti Junction is a nickname sometimes given to a complicated or massively intertwined road traffic interchange that is said to resemble a plate of spaghetti. Such interchanges may incorporate a variety of interchange design elements in order to maximize connectivity.
The Gravelly Hill Interchange in Birmingham, England – the original Spaghetti Junction
Etymology
The term was originally used to refer to the Gravelly Hill Interchange on the M6 motorway in Birmingham, United Kingdom.[1] In an article published in the Birmingham Evening Mail on 1 June 1965 the journalist Roy Smith described plans for the junction as "like a cross between a plate of spaghetti and an unsuccessful attempt at a Staffordshire knot", with the headline above the article on the newspaper's front page, written by sub-editor Alan Eaglesfield, reading "Spaghetti Junction".[2][3][4] Since then many complex interchanges around the world have acquired the nickname.
Throughout North America, this type of interchange is widely referred to as a spaghetti junction, mixing bowl, knot, or maze, often including the name of the freeway, city, or notable landmark near enough to the interchange.
