Spaghetti Junctions: Gravelly Hill Interchange poster

The original spaghetti junction in Birmingham opened in 1972. Encompassing 18 routes in total, it was built to connect the M6, A38(M), A38 and A5127 north of the city centre. The resulting tangled form was given the 'spaghetti junction' label by a journalist, Roy Smith of the Birmingham Evening News for obvious reasons. The name stuck and nowadays few know its real name – Gravelly Hill Interchange. Since then, many spaghetti junctions have been built around the world, some of amazing complexity.

The engineered curves in the carriageways are dictated by the speed of travel; only gentle curves can be navigated at high speed, leading to the flowing appearance of the junction.
