With 139,000 km of public roads, the Netherlands has one of the most dense road networks in the world: much denser than Germany and France, but still not as dense as Belgium. Dutch roads include at least 3,530 km of motorways and expressways, and with a motorway density of 64 kilometres per 1,000 km², the country also has one of the densest motorway networks in the world.The Netherlands' main highway net (hoofdwegennet), comparable to Britains net of trunk roads, consists of most of its 5,200 km of national roads, supplemented with the most prominent provincial roads. Although only about 2,500 km of roads are fully constructed to motorway standards, much of the remainder are also expressways for fast motor vehicles only.
