Paris Is Changing the Way You Reach Charles-de-Gaulle

Paris is about to overhaul its airport links. The Roissybus service between Opéra and Charles-de-Gaulle ends on 1 March 2026. A new system built around a northern hub and faster rail lines is taking its place.

Roissybus was simple for visitors staying in the center. You could walk out of a hotel near Opéra and ride straight to the airport.

Over time, the trip became slow. The A1 jammed up, and the final stretch into central Paris often dragged. Transport officials decided the route no longer worked.

The replacement is line 9517. It will connect CDG with Saint-Denis–Pleyel instead of Opéra. This station is turning into a major interchange. It links metro lines 13 and 14, RER D, and the future Grand Paris Express network.

The idea is to move airport transport to a hub with faster transfers and fewer traffic problems.

This changes your airport journey: you won’t be able to walk out of a central hotel near Opéra and board a direct airport bus anymore. Instead, you’ll take the metro or RER to Saint-Denis–Pleyel, then switch to the 9517 bus.

If you stay stay near line 14 – Châtelet, Pyramides, Madeleine, Gare de Lyon, Bercy, you will have an easy connection. But travelers staying around Opéra or the Grands Boulevards add a short metro ride before the airport link.

Another major step arrives in March 2027 with CDG Express. This new train will run non-stop between Gare de l’Est and CDG Terminal 2 in about twenty minutes. It will operate every fifteen minutes. It will create a fast, reliable option and take pressure off the crowded RER B line.

More changes follow with the Grand Paris Express project. Line 17 will connect CDG to Saint-Denis–Pleyel and later extend toward the west. Sections of this line open between 2027 and 2030. It will introduce new access points to the airport outside the historic center and further shift travel patterns.

For now, RER B remains the main low-cost route between Paris and the airport. Standard regional buses and long-distance coaches continue to run as well.

The next few years will bring a complete reset of how the region handles airport travel, with central Paris gradually stepping back in favor of faster hubs and dedicated rail links.
