London is the starting point for a number of motorway routes. The M25 is an orbital motorway which enables vehicles to avoid travelling through central London and is one of the busiest motorways in Europe.
The London Transport Museum, based in Covent Garden, central London, seeks to conserve and explain the transport heritage of Britain's capital city. The majority of the museum's exhibits originated in the collection of London Transport, but, since the creation of Transport for London (TfL) in 2000, the remit of the museum has expanded to cover all aspects of transportation in the city. Galleries cover subjects including the development of transport in London from the 19th century, the construction and operation of the London Underground, London's bus and tram systems, the expansion of suburban London and transport design.
The museum also operates the London Transport Museum Depot at Acton in west London, which provides 6,000 square metres of storage space for over 370,000 items of all types including very large items such as rolling stock, buses and trams. The depot is no permanently open to the public, but hosts a number of open days throughout the year.
Sir Leslie Patrick Abercrombie (6 June 1879 – 23 March 1957) was an English town planner. After training as an architect, he became Professor of Civic Design at the Liverpool University School of Architecture, and later Professor of Town Planning at University College London. He was closely involved in the founding of the Council for the Preservation of Rural England (CPRE). After its formation in December 1926, he served as its Honorary Secretary. He was knighted in 1945. In 1948, he became the first president of the newly formed International Union of Architects or UIA (Union Internationale des Architectes).
Abercrombie is best known for the post-Second World War replanning of London and other British and international cities. He created the County of London Plan (1943) and the Greater London Plan (1944) which are commonly referred to as the Abercrombie Plan. The two plans proposed widespread reconstruction and replanning of the city and the urban areas of the surrounding counties and road and rail infrastructure including the construction of a series of concentric ring roads and underground rail loops to connect main line stations below ground to replace surface routes.
