bridge
South African National Roads Agency Limited’s N2 Wild Coast Toll Road (N2WCTR) serves as a shining example of a catalytic infrastructure project that combines socio-economic benefits and engineering ingenuity.

The N2WCTR, which stretches from the Gonubie Interchange in East London to the Mtamvuna River near Port Edward, will shorten travel time by up to three hours. The project has created thousands of new jobs, as well as opportunities for SMMEs, women and youth – the benefits of which can and will be seen locally and regionally.  

 

Among the remarkable engineering feats planned within this programme is the construction of Mtentu bridge near Lundini in the Eastern Cape province. Once completed, Mtentu Bridge will be Africa’s tallest bridge at a staggering 223 m high. With a length of 1.13 km, including a 260 m long main span, the bridge will also rank among the world’s longest main-span balanced cantilever bridges.  

 

In August 2023, construction work on Mtentu Bridge commenced following a four-month ramp-up period. As the appointed bridge designers, SMEC South Africa and HVA JV partners CH2M and Axis, have played a pivotal role in the Mtentu Bridge project since its inception. The team is now involved in the construction monitoring and technical support services for the project.  

 

Mtentu is the second mega-bridge in the N2WCTR project and, together with the cable-stayed Msikaba bridge, will form part of the 112 km of new highway between Port St Johns and Port Edward. SMEC South Africa also undertook design and construction monitoring of the Msikaba bridge.
