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).
Charles Henry Holden (12 May 1875–1 May 1960) was an English architect best known for his designs of some of the 1920s and 1930s stations on the London Underground, but who was already a distinguished architect before then, notably for his Imperial War Graves Commission cemeteries in Belgium and northern France.
Many of Holden's later designs for Underground stations went unrealised or were scaled back because of World War II with only East Finchley representative of a series of stations planned for the cancelled extension of the Northern line to Bushey Heath and with stations on the Central line's extension into east London being scaled back by post-war austerity. Modestly believing that architecture was a joint effort, Holden twice declined the offer of a Knighthood. (Full article...)
... that the Royal Commission on London Traffic proposed constructing 9 miles (14 km) of avenues with railways underneath at the cost of £30 million in 1905?

Continuation of the West Cross Route northwards under the roundabout was cancelled leaving two short unused stubs for the slip roads that would have been provided for traffic joining or leaving the northern section.

A60 stock trains operated on the surface and sub-surface sections of the Metropolitan line from 1961 to 2012 and 1938 Stock operated on various deep level tube lines from 1938 to 1988.
