It's the world's longest sea-crossing bridge: 55 kilometres of motorway spans the Pearl River Estuary in the South China Sea before dipping into an undersea tunnel. The Chinese President Xi Jinping has today officially opened the gigantic infrastructure linking Hong Kong, Macau and mainland China. A colossal engineering structure, involving the Bouygues Construction subsidiaries Bouygues Travaux Publics, Dragages Hong Kong and VSL for the construction of a 9.4-kilometre section.
A bridge of strategic importance 5714 prefabricated segments of 250 different types, laid down at the rate of 18 per day, shaft grouted friction piling method to cope with difficult ground conditions – a technical first in Hong Kong –, sea-based installations and specific logistical arrangements to maintain the waterways throughout the duration of the works... Some notable innovations for the construction of this extraordinary bridge structure. It is now possible to reach Hong Kong from the main cities of the Pearl River delta in 30 minutes, compared with four hours by land and one hour by boat. A real basis for stimulating commercial ties between the two sides of the crossing.
