Webuild and its local partner celebrated the breakthrough of their tunnel-boring machine near the end of its underground journey of 4.05 kilometres to help extend Line 14 South in southern Paris for Europe’s most ambitious sustainable mobility project: the Grand Paris Express. The TBM, named Koumba, broke through the wall to arrive at the Europe shaft to the applause of scores of attendees, including representatives of Webuild, Nouvelles Générations d’Entrepreneurs, Webuild’s partner on the project, and the client, Régie Autonome des Transports Parisiens.

Since it began work a little more than a year ago at Puits de Morangis, the 850-tonne TBM has excavated up to 20 metres below Orly Airport as well as set a record by doing 671.47 metres in only 31 days.

Line 14 South will improve connections and travel times between the airport and the city centre by linking the airport to Line 18 of the existing metro network and a new line to be called Line 15.

The Grand Paris Express is extending the French capital’s metro and light rail network by 200 kilometres and 68 stations to improve connections between the centre and the periphery. It is designed to improve the local economy, promote sustainable mobility and reduce vehicle traffic and air pollution as Paris pursues its goal of becoming carbon neutral by 2050.
