Alternative route

In case of major traffic disruption or closure due to maintenance works on RER line B,
we suggest to use Roissybus instead.
Roissybus runs non-stop between Paris-Opéra and CDG Airport in approx. 60 minutes.

You can catch Roissybus at CDG (Terminals 1, 2, 3), in Paris (11 rue Scribe), nearby Auber RER station,
just one stop away to-from Châtelet-Les Halles with RER line A.
