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.

“At the end of the crisis [health linked to the Covid-19 epidemic], the questions [regarding energy policy] will need to be readdressed.” So said Pascal Roger, president of the Federation of energy environment services (Fedene) to News Tank Cities on 01 April 2020. Currently, new renewable energies represent a prospect for ecological transition for this sector with photovoltaic in the lead, between giant power plants and innovative installations. Where are we ?
In Llo, a town in the Pyrenees mountains, France just installed a thermodynamic solar power plant.
By 2050, almost 70% of the world's population will live in cities. But not just any old city, mind you! Cities offering a greener living environment are – and are set to become – increasingly popular. So, let's take a look at the issue of urban planning.
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?
The Fort d’Issy-Vanves-Clamart station took a crucial step in the night of 12-13 August: the 7,000 tonnes of concrete forming the roof were slipped briskly into place by Bouygues Travaux Publics teams.
