Société du Grand Paris has awarded the consortium of Colas Rail and Alstom the contract for the track, overhead contact line and linear equipment for the second section of the Grand Paris Express Line 17. This is one of four new Paris Metro rapid transit lines planned in the Île-de-France region of France.

The Grand Paris Express is an ambitious public transport project currently underway in the Paris region. It aims to improve mobility for the people of the Paris region by building a fast and modern automatic metro system that will link the city’s suburbs and relieve congestion on existing public transport.

This major project, scheduled for completion in 2030, is expected to include four new metro lines and the extension of two existing metro lines, for a total of nearly 200 kilometres of track and more than 60 new stations. The Grand Paris Express is considered one of the most important infrastructure projects in Europe and is expected to significantly impact the lives of the people of the Ile-de-France.

Underground works

Colas Rail will lead the consortium and is responsible for the supply and installation of 10 kilometres of track, overhead contact line and linear equipment between Le Bourget Airport and the Parc des Expositions, located before Roissy. The work will take place in a tunnel, in embankments and on a viaduct over 3 kilometres. Up to 200 employees will be mobilised on this project, which should begin by mid-2024.

The consortium has undertaken to limit its greenhouse gas emissions by supplying low-carbon concrete and rails rolled from steel produced by a less energy-intensive process. Electric vehicles will be used, as well as LEDs for the tunnel lighting. Rainwater will be treated and residues from the concreting of the tracks will be recycled.

Gradual opening of the line

Line 17, 26.5 kilometres long, will cross 13 municipalities and link 9 stations between Saint-Denis Pleyel and Le Mesnil-Amelot in less than 25 minutes. It will serve Le Mesnil-Amelot, Saint-Denis Pleyel, Plaine Saint-Denis, Le Bourget airport and Paris-Charles-de-Gaulle airport, thus facilitating travel for almost 565,000 inhabitants.

The opening of Line 17 will be gradual. The section from Saint-Denis Pleyel to Le Bourget Airport is scheduled to open in autumn 2026, the section from Le Bourget Airport to Parc des Expositions by 2028 for and the section from Parc des Expositions to Le Mesnil-Amelot by 2030.

In the context of the 2024 Summer Olympics, it was planned to open the Le Bourget-Airport station at the same time as the common trunk line with line 16, but delays due to the Covid-19 pandemic prevented this section from being opened on time, which is now expected in autumn 2026.
