Line 15 South, the next stage of the future Grand Paris Express

Ile de France / France

Project manager: Société du Grand Paris

Bouygues Travaux Publics is involved in the construction of Line 15 South of the Grand Paris Express with lots T2A, T3A and T3B. A total of 12 kilometres of tunnels will be dug by four tunnelling machines on these three lots. As part of the Horizon consortium, Bouygues Travaux Publics will also be responsible for the construction of seven railway stations. The T2A project has been awarded the TopSite label in recognition of all aspects of CSR being taken into account in this large-scale project, which is subject to considerable constraints in a very dense urban area and a high level of shared activity with the SNCF rail network. These sections of Line 15 South will offer real alternatives to travelling by car and improve access to major public facilities such as the Institut Gustave-Roussy cancer centre in Villejuif and the Henri-Mondor hospital in Créteil.

“The Grand Paris Express is the expression of what we are trying to create for the Paris of the future: these infrastructure works are set to transform the lives of the people who live there for years to come.”
