The only four-level stack interchange in South Africa has been given various nicknames, the most famous one is Spaghetti Junction.

The N2 connects Cape Town with Durban, and it serves other South African cities as well, such as Port Elizabeth, East London, George and the towns of Mthatha, Port Shepstone and Richards Bay and iSimangaliso Wetland Park.

A four-level stack interchange was chosen for this junction to serve the high volumes of traffic.
