Roads in the United Kingdom form a network of varied quality and capacity. Road distances are shown in miles or yards and UK speed limits are in miles per hour (mph) or use of the national speed limit (NSL) symbol. Some vehicle categories have various lower maximum limits enforced by speed limiters. Enforcement of UK road speed limits increasingly uses speed guns, automated in-vehicle systems and automated roadside traffic cameras. 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 survive and others were lost. New roads were added in the mediæval period and from the 17th century onwards. Whilst control has been transferred from local to central bodies and back again, currently management and development of the road network is shared between local authorities, the devolved administrations of Scotland, Wales and Northern Ireland and the Highways Agency. Certain aspects of the legal framework remain under the competence of the United Kingdom parliament.
Although some roads have much older origins, the network was subject to major development from the 1950s to the mid-1990s. From then, construction of roads has become increasingly controversial with direct action campaigns by environmentalists in opposition.

Famous quotes containing the words roads, united and/or kingdom:
“I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.”
—Robert Frost (1874–1963)
“What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.”
—Henry David Thoreau (1817–1862)
“There exists a black kingdom which the eyes of man avoid because its landscape fails signally to flatter them. This darkness, which he imagines he can dispense with in describing the light, is error with its unknown characteristics.... Error is certainty’s constant companion. Error is the corollary of evidence. And anything said about truth may equally well be said about error: the delusion will be no greater.”
—Louis Aragon (1897–1982)
