Roads in the United Kingdom

rdf:langString Roads in the United Kingdom

rdf:langString The United Kingdom has a network of roads, of varied quality and capacity, totalling about 262,300 miles (422,100 km). Road distances are shown in miles or yards and UK speed limits are indicated in miles per hour (mph) or by the use of the national speed limit (NSL) symbol. Some vehicle categories have various lower maximum limits enforced by speed limiters. A unified numbering system is in place for Great Britain, whilst in Northern Ireland, there is no available explanation for the allocation of road numbers. The earliest specifically engineered roads were built during the British Iron Age. The road network was expanded during the Roman occupation. Some of these roads still remain to this day. New roads were added in the Middle Ages and from the 17th century onwards. Whilst control has been transferred between local and central bodies, current management and development of the road network is shared between local authorities, the devolved administrations of Scotland, Wales and Northern Ireland, and National Highways (England). Certain aspects of the legal framework remain under the control of the United Kingdom parliament. Although some roads have much older origins, the network was heavily developed from the 1950s to the mid-1990s to meet the demands of modern traffic. Construction of roads has become increasingly problematic with various opposition groups such as direct action campaigns and environmentalists. There are various ongoing and planned road building projects. In the UK, road safety policy is part of transport policy. "Transport 2010; The 10 Year Plan" states that the basic principle is that "people travel safely and feel secure whether they are on foot or bicycle, in a car, on a train, or bus, at sea or on a plane".
