Project Detail
Based on its preliminary traffic assessment to determine the current and future capacity of the route, Mariswe recommended that the road be upgraded from single carriageway to a four-lane dual carriageway.
Mariswe was then appointed to provide the engineering services for the 33.7 km upgrade. This section of the N2, the final link between Durban and the towns of Empangeni and Richards Bay, has traffic volumes in excess of 12 000 vehicles per day.
The project involved construction of a new two-lane carriageway for northbound traffic and rehabilitation of the existing carriageway, reconfigured to two lanes, for southbound traffic.
Extensive bridge work, including construction of a four-span bridge over the Mlalazi River and an eight-span bridge over the Mhlatuze River, new bridges at interchanges, extensions to existing overpasses and two new road-over-rail bridges, was designed by Mariswe’s Structures team.
Mariswe provided training to 10 SANRAL project managers registered with ECSA as candidate engineers as part of the project.
