 South of the River Thames, the ECR (A102) skirts Tunnel Avenue and flies over Blackwall Lane (A2203) and Woolwich Road (A206) before climbing the hill towards the Sun-in-the-Sands interchange where it passes under Shooters Hill Road (A2/A207) and becomes the Rochester Way Relief Road (A2).It squeezes through the tight space between Rochester Way (the old A2 route) and Woolacombe Road before it ends at the Kidbrooke interchange where it connects to Kidbrooke Park Road (A2213) or continues as the later section of the Rochester Way Relief Road built in the 1980s.The ECR and the other roads planned in the 1960s for central London which formed Ringway 1 of the London Ringways scheme 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" to a 1960s Greater London Council (GLC) scheme that would have involved the construction of many miles of motorway standard roads across the city and demolition on a massive scale.
