Two busy roads intersect at the junction. A four-level stack interchange was chosen to serve the high volumes of traffic. The Mount Edgecombe Interchange is another four-level stack interchange just outside Durban, South Africa, and is the intersection between the N2 (to Durban and KwaDukuza) and the M41 (to Mount Edgecombe and uMhlanga). The ...
The first stack interchange in the world was the Four Level Interchange (renamed the Bill Keene Memorial Interchange), built in Los Angeles, California, and completed in 1949, at the junction of U.S. Route 101 and State Route 110. [3]
There are some stacks that could be considered 5-level; however, these remain four-way interchanges, since the fifth level actually consists of dedicated ramps for HOV/bus lanes or frontage roads running through the interchange. The stack interchange between I-10 and I-405 in Los Angeles is a 3-level stack, since the semi-directional ramps are ...
The High Five Interchange is one of the first five-level stack interchanges built in Dallas, Texas. Located at the junction of the Lyndon B. Johnson Freeway ( Interstate 635 , or I-635) and the Central Expressway ( U.S. Highway 75 , or US 75), it replaces an antiquated combination interchange constructed in the 1960s.

This marked the first time the entire Loop 303 between I-10 and I-17 was fully upgraded to freeway standards. [3] In February 2016, construction began on the south half of the I-10 and Loop 303 stack interchange.
