Roissy-Charles de Gaulle airport: metro line 17 arrives in 2027 for a direct journey from Paris

Travelers will soon be able to reach Roissy-Charles de Gaulle airport by metro. This new line promises to revolutionize journeys to France’s largest airport. For millions of users, this announcement is a game-changer.

Line 17 of the metro will finally connect Paris to Roissy

The Grand Paris Express is making great strides. Among the flagship projects, line 17 of the network stands out for its ambition. It will link the north of Paris directly to Roissy-Charles de Gaulle airport, a major hub for European air traffic.

The new underground infrastructure will be 27 kilometers long. It will serve several municipalities in Seine-Saint-Denis and Val-d’Oise. Residents of these areas will benefit from easier access to the airport and Paris.

At present, the RER B is the only rail link to Roissy. This line suffers from frequent saturation at rush hour. What’s more, delays are recurrent, annoying passengers in a hurry.

“This line represents a major turning point for mobility in the Île-de-France region and for all daily users.”

A project long-awaited by travellers

Ile-de-France residents have been waiting a long time for this direct link. The project has been postponed several times. Work has now begun, but the timetable remains tight if the announced deadlines are to be met.

Progressive commissioning is scheduled to take place by 2030. The first sections will open before then. As a result, some users will benefit from this new service sooner than expected.

• Line 17: 27 km of fully automated track
• 9 stations planned between Saint-Denis Pleyel and Le Mesnil-Amelot
• Shorter journey times to Roissy-CDG
• Connections with lines 14, 15, 16 and RER B
• High frequency to absorb passenger flow

What are the concrete benefits for everyday users?

The first benefit is time savings. From now on, journeys between Paris and Roissy will take less than 30 minutes. This speed will appeal to tourists and business travellers alike.

Comfort promises to be even better than with the RER B. The trains will be new and air-conditioned. What’s more, the network will be driverless, guaranteeing high levels of regularity.

For people living near the stations, this line represents a real opportunity. Access to employment will be easier. The economic zones around Roissy are recruiting massively, and this direct link will simplify hiring.

Air travelers, on the other hand, will gain in serenity. Missing a flight because of a late train remains a frequent nightmare. With this new metro line, this stress should be reduced.

A credible alternative to the CDG Express

The CDG Express, another current project, targets a premium clientele. Its fare will be around 24 euros per journey. The metro, on the other hand, will remain accessible with a simple Navigo ticket.

This price difference is important to many travelers. Families or students will logically prefer the cheapest option. So, line 17 meets a mobility need for all.

Yet the two solutions will coexist without really competing. Each is aimed at a distinct audience. The CDG Express focuses on speed and top-of-the-range comfort.

A colossal project transforming the northern Paris region

Thousands of workers are mobilized every day. Tunnel boring machines (TBMs) excavate the subsoil at a steady pace. These impressive machines advance several meters per week.

Future stations are gradually taking shape. Some stations, like Le Bourget Aéroport, will accommodate several lines. This multimodal hub will become a strategic crossroads.

Construction site nuisance remains a sensitive issue for local residents. Noise and machine traffic disrupt daily life. However, crews are limiting night-time work to minimize inconvenience.

The Société du Grand Paris is piloting this titanic project. Its total budget exceeds 35 billion euros for the entire network. Line 17 represents a significant part of this investment. Thanks to this new metro, the Paris region will enter a new era of urban mobility.
