Name of the Project
N2 Wild Coast Toll Road (N2WCTR) megabridges project.

Location
The bridges will be built over the Msikaba river gorge, in Xolobeni, and the Mtentu river, near Lusikisiki, in South Africa’s Eastern Cape province.

Client
South African National Roads Agency Limited (Sanral).

Project Description
The Msikaba and Mtentu bridges form the backbone of the greenfields portion of the N2WCTR project – one of government’s 18 Strategic Integrated Projects. The greenfield section of the N2WCTR extends from Port Edward, in KwaZulu-Natal, through to Port St Johns, in the Eastern Cape. This section is a new road and, without the bridges, will not be able to be completed.

The 1.13-km-long Mtentu bridge will be one of the longest main-span-balanced cantilever bridges in the world. Reaching heights of about 220 m, it will secure the title as the highest bridge in Southern Africa with its 217 m deck height.

The 580-m-long Msikaba bridge will be the longest-span cable-stayed suspension bridge in South Africa, and possibly Africa.

The cable-stayed design will ensure that the construction of the bridge will have no direct impact on the gorge environment 200 m below, which is one of the environmental requirements in building the bridge.

Pedestrian sidewalks and view sites, which will provide special viewing points for tourists, will be built on either side of the bridges.

Jobs to Be Created
Semiskilled and unskilled labour will be sourced locally.

Value
The Mtentu bridge will cost R1.634-billion. The Msikaba bridge tender has not been awarded yet.

Duration
Construction of the Mtentu bridge will start in November and is scheduled to last for about 40 months.

Latest Developments
Sanral has awarded the tender for the Mtentu bridge to the Aveng Strabag joint venture (JV), comprising South Africa-based Aveng Grinaker-LTA and European group Strabag. Strabag has extensive experience in major balanced cantilever methodology bridge construction.

The tender for the Msikaba bridge will be re-issued, owing to Sanral’s not having received fully responsive tenders. The agency said in July that the new tender for the bridge would be advertised in the next two to three months.

Key Contracts and Suppliers
Aveng Strabag joint venture (Mtentu bridge).

On Budget and on Time?
