This option costs EUR Eur 4.90, a ticket for zones 1-4. This option is useful to get out of the ring roads and get directly on the A10 after all the branch-offs.

Take RER B to Massey-Palaiseau station. Walk down Avenue Carnot along the Massy-Palaisea' railway towards the ''autoroute''. After a while there you will see a long stretch of a road with lots of space for cars. Keep going and you will reach a roundabout. If you keep following this road, you will reach the motorway entrance underneath a bridge. Make sure to get a ride to the first ''barrière de péage'' (30+ km) at St-Arnoult or to the Limours-Janvry service station 5 km down the road.
