Boulevard Périphérique

Alors, the Paris freeway network! A freeway, the Boulevard Périphérique, travels a ring around the city, and key roads that transect and travel to and from the heart of the city are accessed off the ring at well-marked portals or "portes." When leaving Paris, autoroutes spoke out to the north, south, east and west from the "portes," identified by major destinations beyond the city limits. Basically, whether leaving or returning to Paris, merge onto the Boulevard Périphérique and travel it until you reach the appropriate "porte." The "portes" are evenly distributed along the boulevard; all you have to do is choose the "porte" closest to your final destination. To give you an appreciation for the immensity of the Boulevard Périphérique, if you miss an exit, it will take you over an hour to drive round back to the same point. Therefore, if you do miss an exit, it is best to exit at the next one and detour back!
