The project includes the construction for the elevated section of line 17 and the first elevated station of the Grand Parix Express: « Parc des Expositions » next to the Villepinte Exhibition Centre. NGE will also carry out landscaping work for which fertile soils excavated during the works will be mostly recycled.
It includes a 3km-long metal viaduct, 2 road overpasses over A1/A3 motorway (200 m long) and RD40 south road (145 m long) and 4 earth structures.
This project highlights NGE’s Multi-disciplinary services, as it involves several expertise of the Group: civil engineering, building, earthwork and landscaping, and foundations to build the 5km elevated metro section between the cities of Gonesse and Tremblay-en-France, located north of Paris.
