There are ~950,000 km of roads in France. It has the 8th largest highway network in the world. France currently counts 30,500 km of major trunk roads or routes nationales and state-owned motorways. By way of comparison, the routes départementales cover a total distance of 365,000 km. The main trunk road network reflects the centralising tradition of France: the majority of them leave the gates of Paris. Indeed, trunk roads begin on the parvis of Notre-Dame of Paris at Kilometre Zero. To ensure an effective road network, new roads not serving Paris were created.
