New Express Bus Line 9517 to Roissy CDG Airport: Your Practical Guide
As of March 1, 2026, the popular RoissyBus shuttle will cease operations, making way for a new express bus service: line 9517. This new route offers a vital alternative for travelers heading to or from Roissy-Paris-Charles de Gaulle Airport, connecting Argenteuil and Saint-Denis-Pleyel directly to Roissypôle, just a short walk from the airport terminals.
Why the Change?
The RoissyBus, which has long served as a direct link between Opéra in Paris and Roissy CDG, is being replaced to optimize public transport options. The new 9517 line aims to provide a convenient and efficient solution for residents and tourists alike, particularly those in the northern and western suburbs of Paris.
