The London Ringways were a series of four ring roads planned in the 1960s to circle London at various distances from the city centre. They were part of a comprehensive scheme developed by the Greater London Council (GLC) to alleviate traffic congestion on the city's road system by providing high-speed motorway-standard roads within the capital, linking a series of radial roads taking traffic into and out of the city.
There had been plans to construct new roads around London to help traffic since at least the 17th century. Several were built in the early 20th century such as the North Circular Road, Western Avenue and Eastern Avenue, and further plans were put forward in 1937 with The Highway Development Survey, followed by the County of London Plan in 1943. The Ringways originated from these earlier plans, and consisted of the main four ring roads and other developments. Certain sections were upgrades of existing earlier projects such as the North Circular, but much of it was new-build. Construction began on some sections in the 1960s in response to increasing concern about car ownership and traffic.
