The Msikaba Bridge construction will begin in February 2019 after a successful tendering process.
The South African National Roads Agency (SOC) Limited (SANRAL) has announced that the tender for the second of two mega-bridges that are part of the N2 Wild Coast project has been awarded.
The bridge will be built near Lusikisiki over the Msikaba gorge.
Construction on the nearby Mtentu River Bridge began in January this year. Both form part of the future new N2 Wild Coast Road.
The successful bidder was Concor Mota-Engil Joint Venture – a strategic partnership between Concor – a large and majority black-owned South African civil engineering company – and Mota-Engil – a major international construction firm.
Concor brings a proven track record in the construction of major roads and bridge projects in South Africa and Africa, while Mota-Engil has experience in large-scale cable-stayed bridge projects and delivery of major civil engineering projects throughout Africa.
The construction is due to start in February 2019 and will take 33 months after an initial three-month ramp-up period starting in October 2018.
The total contract amount is approximately R1.65-billion excluding VAT.
The tender award comes after the agency announced in July 2017 it had to be re-advertised as SANRAL received no fully responsive tenders for the initial bid.
The tender was re-advertised on 3 November 2017 and closed on 11 April 2018. The long period was required due to the size and complexity of the tender.
