Express Line 9517: the new fast bus to Paris - Charles de Gaulle Airport
Since March 1, 2026, Express line 9517 has been revolutionizing travel between Argenteuil, Saint-Denis Pleyel and Paris - Charles de Gaulle Airport. Modern, comfortable and fast, this express bus is becoming an essential solution for reaching the Roissy terminals.
A strategic route for Île-de-France travelers
Line 9517 serves several key stops to make connections easier:
- Argenteuil: starting point of the line and connection with the Transilien line
- Saint-Denis Pleyel: multimodal hub with RER lines
and metro lines

With an average journey time of 1h10 from Argenteuil and 50 minutes from Saint-Denis Pleyel, Express line 9517 is a fast and cost-effective alternative for getting to the airport!
Good to know 💡: this line does not stop at the various terminals; you will need to take the CDGVAL for that.
