Grand contournement de Paris or Big -pass of Paris refers to a chain of highway routes, which are collectively referred to as the fourth ring road around Paris, while the third ring road of francilienne enclose a large distance of 80 km to 200 km. Further inside the beltway Autoroute A86 is located at a distance from the Notre Dame 8-16 km away and the Boulevard périphérique, which runs directly to the city limits of Paris.

The basis of the Great bypass is the centralized structure of France, in which almost all paths are designed to lead to and from Paris. For instance, also the road network, do not want to enter in the Ile- de -France region, yet go there and find a motorway connecting rings in an outgoing highway. With the Great bypass but can be changed from one to another focused on Paris highway without driving into the gridlocked Paris region.

The first variant extends down to the joint with the second variant section east of Paris approach in the other three directions up to 80 kilometers of Paris. The second variant is almost circular and runs it at a distance of 140 (northern section) to 240 (southern section ) kilometers to Paris.
