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.

Stéphane Allaire, chairman of Objenious, tells us about the activities, positioning and the technology from this Bouygues Telecom start-up.
Although cities occupy a mere 2% of the surface of the planet, they consume 75% of its resources, emit between 60% and 80% of anthropogenic greenhouse gases and generate 50% of waste . Cities are a privileged gateway for the entry and exit of a large concentration of flows (food, electricity, cold, heat, fuel, consumer goods, waste, etc.) that enable them to meet the needs of their users: remember that cities today account for 55% of the world population. The study of these flows according to the principles of urban metabolism is a field that is growing in popularity. More and more urban authorities are using it as a basis for defining their circular economy policies.

Responsible for 67% of global GHG emissions, cities are on the front line of this challenge. Two high-emissions sectors - transport and construction - are of direct concern to them. What are their margins of manoeuvre and trajectories to become low carbon and carbon neutral? What are the major assets of the local scale?
