The M25 or London Orbital Motorway is a 117-mile (188 km)
motorway that encircles almost all of
Greater London, England (with the exception of
North Ockendon), in the United Kingdom. An ambitious concept to build
four concentric ring roads around London was first mooted in the 1960s. A few sections of the outer two rings were constructed in the early 1970s, but the plan was abandoned and the sections were later integrated to form a single ring which became the M25, completed in 1986.
It is one of the busiest of the
British motorway network: 196,000 vehicles were recorded on a busy day near
Heathrow Airport in 2003 and the western half experienced an average daily flow of 147,000 vehicles in 2007. To alleviate congestion, sections of the motorway have been widened from the original three-lane carriageways to four-, five- or six-lane carriageways. Other sections use
Smart motorway operation with hard shoulders replaced with standard lanes.
The M25, plus the short non-motorway A282 which joins the two ends of the M25 across the
River Thames using the
Dartford Crossing, is Europe's second longest orbital road after the
Berliner Ring, which is 122 miles (196 km).

Henry Charles Beck (4 June 1902 – 18 September 1974), known as Harry Beck, was an English
technical draughtsman best known for creating the present
London Underground
Tube map in 1931. Beck drew up the diagram in his spare time while working as an engineering draftsman at the London Underground Signals Office. London Underground was initially sceptical of Beck's radical proposal, an uncommissioned spare-time project, but tentatively introduced it to the public in a small pamphlet in 1933.
Beck's approach to the map was to remove all geographical content except the River Thames so that the focus could be on the arrangement of lines and stations and to enable the central area to be expanded map. Beck first submitted his idea to
Frank Pick in 1931 but it was considered too radical because it didn't show relative distances between stations. After a successful trial of 500 copies in 1932, distributed via a select few stations, the map was given its first full publication in 1933 (700,000 copies). It was immediately popular, and the Underground has used
topological maps to illustrate the network ever since.
Beck's contribution to the visual style of London Underground is recognised with a plaque at what was his local Underground station,
Finchley Central; with a
blue plaque at his birth place in
Leyton and the Beck Gallery at the
London Transport Museum. (
