Motorway megaproject in Mauritius
Port Louis, Mauritius
Upon completion, the bridge will link two of the country’s most important highways, while helping commuters to avoid the long and often steep roads, that traverse the nearby valleys and canyons. By presenting the best technical design solution, Doka was awarded the full scope of work to support the delivery of this highly complex piece of engineering, which included a broad range of new and used material. Designed around a two-pier structure, with the highway suspended from pylons at a height of 90 metres, Doka’s engineers had to factor in seasonal weather conditions such as cyclones, which have already tested the project’s design with winds reaching in excess of 190 km/h.
