This description begins at the southern end of the route and travels north.
Beginning in Wandsworth, and continuing west from Ringway 2's Southern Section, the Western Section would depart Wandsworth Interchange by joining the north side of the rail line from Waterloo towards Richmond - a four-track railway known as the "Windsor Lines". All the houses on the south side of Disraeli Road and Norroy Road would have been demolished to make way for the motorway, while the houses on the north side of those streets would only have been saved if a way were found to build a retaining wall to support them from below, and the street itself was then projected out above the motorway. That's what an ambitious set of engineering cross-sections from 1965 show, but it would be a formidable engineering challenge and perhaps the more likely outcome (especially considering much cheaper 1960s property prices) would simply be to demolish the lot.
Continuing west along the railway, the motorway would follow the south side of Clarendon Road and Dryburgh Road, emerging from its cutting to run at ground level. Here, long back gardens meant the houses themselves might have been saved, but dining rooms and kitchens would have looked out on to the hard shoulder.
The motorway would then run through Barnes Common, adjacent to the railway station, and join the north side of the railway towards Hounslow. Plans here vary; in 1965 the motorway was planned to simply run at ground level, but in later years (as the opposition to the motorway became more apparent) there are suggestions that it might have been placed in cut-and-cover tunnel below the Common. Some documents refer to the possibility of a local interchange with the A306 Rocks Lane but this seems not to have been part of the official proposals.
From this point to the A316, official plans released to the public showed a gap in the route, with a pair of arrowheads vaguely pointing to each other across Barnes. But a route, described below, did exist, and was officially safeguarded from development in 1965. By 1968 there were detailed engineering drawings of it. In mid-1969, a route study considered a different line, running along the south side of the Thames through Mortlake and Kew, but that was rejected as being worse in every possible way, and the safeguarded line was endorsed once again. Still the secrecy was maintained, with the GLC insisting in public that it was "under investigation". Then, in July 1970, knowing just how controversial the motorway slicing through Barnes would be, a meeting was held to discuss the route. It was decided that the official line - which was not really under investigation and had been fixed for five years by that point - would remain secret until the conclusion of the GLDP Inquiry.
Through Barnes, the west side of Cleveland Gardens would be lost, and where it crossed Barnes Terrace - a street of colourful historic buildings lining the riverfront - two Georgian Houses, numbers 13 and 14, would be dismantled and relocated. The motorway would then cross the Thames adjacent to the railway bridge, taking a slice off the sports fields to reach the A316 Great Chertsey Road at Duke's Meadow. Running at ground level, the motorway would pass beneath the A316, which is raised up to cross the railway. Some plans show a three-level stacked roundabout interchange here, with the roundabout above both roads, but the final design appears to be a free-flowing junction with some sliproads passing below the railway and motorway and others above.
Streets and houses immediately north of the railway line through Chiswick would be lost, with the motorway beginning to curve towards the north-west around Whitehall Park Road. This curve would allow it to meet the North Circular Road just north of Chiswick High Road and the A4.
The exact shape and form of the interchange between Ringway 2 and the M4/A4 does not appear to have ever been fully settled. The standard procedure at the time was for the Ministry of Transport to take responsibility for interchanges with trunk roads - and the M4 was a trunk road, so that would ordinarily make it their problem. But unusually, the Ministry and the GLC agreed that Chiswick Interchange would be the GLC's responsibility. The GLC, accordingly, drew up some plans, but no decision on a final layout was recorded. The one shown on the map above is from the 1969 route study.
Of the three plans that have come to light, two see Ringway 2 passing over or under Chiswick Roundabout and appear in material supplied to the GLDP Inquiry panel to support objectors' statements, and their origins are obscure. However, written descriptions of Ringway 2 in this area invariably mention that it would pass east of the roundabout, joining the North Circular Road at the eastern edge of Gunnersbury Park, so the most likely scheme was the third, which appears in a GLC planning document. It sees the motorway passing east of the junction, on the line of Silver Crescent, with sliproads woven through the surrounding urban area, mostly following looping and curving railway tracks.
North of the interchange, Ringway 2 would join the North Circular Road, completing the circuit around London.
The Chiswick triangle
The late 1960s were not a time to be a resident of Chiswick. A suburban district of pleasant semi-detached houses and prosperous families lay between Hogarth House and the Thames, but its attractive location put it in the firing line. It lay between a number of other places where a motorway would be much more difficult to build, it had the A4 and A316 already passing through, and a convenient railway line alongside which Ringway 2 could run. The unfortunate result was that, between the Ministry's intention to upgrade the A4 and A316 to major dual carriageways, and the GLC's plan to build its ring road beside the railway, the entire suburb was set to be carved up to make space for a huge motorway interchange complex.
The outcry from locals was just as sharp and indignant as before. Recognising a losing battle, the engineers thought again, and the final outcome of the study instead recommended new railway and bus services along with a new road in a deep bored tunnel. It would have run roughly on the line of Ringway 2 between Chiswick and Wandsworth, but entering tunnel just south-east of the M4, passing beneath Chiswick, the Thames and Barnes, and surfacing just long enough to interchange with a spur road towards Barnes and the A205 before going back underground. It would then run east underneath the Thames all the way past Putney, finally emerging on the waterfront at Wandsworth.
This tunnelled road might have made things better on the parts of the South Circular it bypassed, but it would have been an astonishingly expensive way to do it. In 1990, with local elections fast approaching and opposition to the road plans continuing to mount, the Transport Minister Cecil Parkinson cancelled the tunnel scheme, and with it any prospect of Ringway 2 returning to West London.
