Paris Ile-de-France Road Network and Travel

The Autoroute system in France consists largely of toll roads, except around large cities and in parts of the north. It is a network of 12,000 km (7,450 miles) worth of motorways.

Unlike other highway systems, there is no systematic numbering system, but there is a clustering of Autoroute numbers based on region. A-1, A-3, A-4, A-5, A-6, A-10, A-13, A-14, A-15, A-16 radiate from Paris with A-2, A-11 and A-12 branching from A-1, A-10 and A-13, respectively. A-7 begins in Lyon, where A-6 ends, as for the A-8 and A-9, which respectly begins near Aix-en-Provence and Avignon. The 20s are found in northern France. The 30s are found in Eastern France. The 40s are found near the Alps. The 50s are near the French Riviera. The 60s are found in southern France. The 70s are found in the centre of the country. The 80s are found west of Paris.

The status of motorways in France has been subject of debate through years, from their construction until recently. Originally, the Autoroutes were built by private companies mandated by the French government, and followed strict construction rules as described below. They are operated and maintained by mixed companies held in part by private interests and in part by the state. Those companies hold concessions, which means that Autoroutes belong to the French state and their administration to semi-private companies.

France has one of the highest set speed limits for limited access roads in Western Europe:
