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.
In May 1938, Sir Charles Bressey and Sir Edwin Lutyens published a Ministry of Transport report, The Highway Development Survey, 1937, which reviewed London's road needs and recommended the construction of many miles of new roads and the improvement of junctions at key congestion points. Amongst their proposals was the provision of a series of orbital roads around the city with the outer ones built as American-style Parkways – wide, landscaped roads with limited access and grade separated junctions.
The Ringway plan had developed from early schemes prior to the Second World War through Sir Patrick Abercrombie's County of London Plan, 1943 and Greater London Plan, 1944. One of the topics that Abercrombie's two plans had examined was London's traffic congestion, and The County of London Plan proposed a series of ring roads labelled A to E to help remove traffic from the central area.
Even in a war-ravaged city with large areas requiring reconstruction, the building of the two innermost rings, A and B, would have involved considerable demolition and upheaval. The cost of the construction works needed to upgrade the existing London streets and roads to dual carriageway or motorway standards would have been enormous. Abercrombie's plans were not intended to be carried out immediately but were, instead, an examination of the longer-term options for the future. The post-war austerity period meant that very little of his plan was carried out.
