DISSING+WEITLING architecture has designed two major bridge structures for the N2 Wild Coast Toll Road in the Eastern Cape Province on the east coast of South Africa. The size and complexity of the two bridges are beyond anything built previously in Southern Africa. The Msikaba Bridge is a 580 metres long cable-stayed road bridge spanning across a spectacular steep green gorge created by the Msikaba River. The Mtentu River Bridge, also designed by DISSING+WEITLING architecture, is a concrete structure approximately 1,130 metres long comprising a 260 metres main span constructed as a balanced cantilever with main piers approximately 160 metres high, plus approach viaducts constructed using incremental launching methods. All set in a truly stunning landscape.
The bridges are part of a larger infrastructural project, the 410 kilometres N2 Wild Coast Toll Road from East London to Mtamvuna near Durban, containing the Msikaba Bridge, the Mtentu Bridge, as well as seven additional major river bridges, aimed at drastically improving the infrastructural connections in the area. The N2 Wild Coast Toll Road is not only a road project but also a catalyst for other development in the region, improving access, mobility and connectivity and creating better opportunities for eco-tourism and conventional tourism in the area. Once complete, the route will be approximately 85 kilometres shorter than the current route and up to three hours faster, improving connectivity for particularly heavy freight vehicles distributing goods.
The project, commissioned by SANRAL (The South African National Roads Agency), has been on hold for almost a decade, but now the funding is in place and the project up and running again. In April 2016, a prequalification bid invite for potential contractors to build the Msikaba and/or the Mtentu bridges was advertised by SANRAL and they will announce the successful incumbents towards the end of 2016. Construction will start in early 2017 with project completion expected for 2022.
DISSING+WEITLING architecture har tegnet to store broer i Sydafrika. Broerne er en del af en større infrastrukturel udvikling i området. Projektet har været på standby i omkring et årti, men er nu igang igen. Anlægsarbejdet begynder i starten af 2017.
