SOCIÉTÉ du Grand Paris (SGP) has awarded a consortium led by NGE and including CIMOLAI a €328 million contract for the construction of 5 km of elevated railway track on three structures for line 17 of the Grand Paris Express project.

The contract also includes the construction of the first elevated Grand Paris Express station at the Parc des Expositions, next to the Villepinte Parc des Expositions.

The 5 km aerial railway will be built between Gonesse and Tremblay-en-France, north of Paris. A 3 km metal viaduct and a 200 m long road viaduct will be built on the A1/A3 motorways and a 145 m long structure on the RD40 south. Finally, four structures will be built in the embankment ranging from 100m to 1km in length.

Construction is expected to begin in April 2022 and be completed in 2029.

The civil engineering will be carried out by NGE Génie Civil as project manager, while the earthworks and landscaping will be carried out by Guintoli. The foundations will be carried out by NGE Fondations and the works will be carried out by NGE Bâtiment. The metal structures will be made by CIMOLAI.

This project is located in the central part of line 17 and is part of the service plan for the major economic centers in the north of the French capital, such as Le Pleyel, Le Bourget airport and Roissy- Charles de Gaulle.

Line 17 is a 20.5 km line with six stations. It is divided into two sections, Line 17 North and Line 17 South. The commissioning of line 17 North is planned in phases, with the section between Saint-Denis Pleyel and Le Bourget RER scheduled for 2024, Le Bourget airport to Triangle de Gonesse scheduled for 2027 and the final section to at the Mesnil-Amelot station in 2030.
