The Gravelly Hill Interchange in Birmingham, England - the original Spaghetti Junction

"Spaghetti Junction" is a nickname sometimes given to a complicated or massively intertwined road traffic interchange that resembles a plate of spaghetti. They incorporate a variety of interchange design elements in order to maximize connectivity.

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.

Japan, somewhat colloquially, has adopted the term tentacle junction in lieu of the Western phrase.

  • Red Cow interchange is a major road junction in west Dublin, Ireland on the M50, meeting the N7 Naas Road (to Cork and Limerick) at a free-flow grade separated junction which incorporates a light railway line. The junction was approved and built between 1972 and 1973 to help accommodate the increased flow of traffic coming into Dublin from commuter areas to the west of the city.

  • The intersection between the A51 motorway (Tangenziale Est Milano), and provincial roads SP2 (Strada provinciale Monza-Bellusco) and SP45 (Strada provinciale Villasanta-Vimercate) is a well-known spaghetti junction in the north-east of Milan. It is locally known as Incrocio delle Torri Bianche in reference to the nearby Torri Bianche commercial district in Vimercate, or Le Montagne Russe ('the roller coaster'). The spaghetti junction evolved around a much simple roundabout intersection which existed before the construction of the Torri Bianche district, and was referred to locally as Rondò dell'Esselunga, in reference to a nearby supermarket.
