Project overview

The extension of this line to the west of Paris requires the construction of new underground infrastructure: the construction of a tunnel of around 8 km, special connection facilities at the stations of Nanterre-la-Folie and Hausmann-Paris-Saint-Lazare and the creation of two underground stations, one at Porte Maillot, the other at La Défense, under the Centre of New Industries and Technologies (CNIT).

Our missions

Egis is providing design and construction engineering works of underground infrastructure. A considerable technical challenge, with regard to the creation of «cathedral» stations and the management of risk in an urban environment with difficult access. Start-up scheduled for 2020!
