Chinese technology and speed reshaping one of SA's busiest freeway intersections

Wang said the need for the upgrade to the interchange was clear when considering the growth of logistics activity linked to the port.

The R4-billion upgrade of the EB Cloete Junction, which links the N2 and N3 highways, is reshaping what has long been known as Spaghetti Junction into a modern transport gateway.

He explained that the redesigned interchange will ultimately feature 32 lanes, seven new overpasses and a cable-suspended iconic arch.

The entire structure is being widened, with additional lanes added on both the inside and outside approaches to ease congestion and remove longstanding bottlenecks. Instead of the usual four lanes, it will be widened to six lanes.

“With us widening the entire interchange and the run to the interchange by one new lane on the inside and one new lane on the outside, we are freeing up that traffic jam,” said Wang.

What makes the project particularly complex is that construction is taking place while traffic continues to move through the interchange. Bridge decks are being widened and lifted without shutting down the flow of vehicles.
