Durban just added an impressive architectural and engineering marvel to its portfolio of landmarks. The Mount Edgecombe highway interchange was officially opened by transport minister Blade Nzimande and the South African National Roads Agency (Sanral) on Wednesday.

The interchange boasts a first for Africa, according to Sanral CEO Skhumbuzo Macozoma in an interview with the state broadcaster. He says it features the continent’s longest flyover ramp that stretches for one kilometre, linking the M41 eastbound with the N2 southbound, connecting surrounding areas like Phoenix and Umhlanga with Durban.

The agency undertook major upgrades to the interchange from April 2013 to ease "chronic congestion of traffic" in the area, notorious for long waiting times, especially during the festive season, when South Africans flock to the coastal region.
The agency intends cutting travel time between the areas the interchange links from 25 minutes to one minute on average. The old interchange had traffic lights increasing waiting time; it has now been converted to a completely free-flowing system with limited stops, says Henk Kaal, resident engineer on the project.
