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 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. Following the campaign by Homes before Roads, the scheme was cancelled in 1973 at which point only three sections had been constructed.
