 Heading south from the A2, Ringway 2 would have crossed golf courses and sports grounds west of Avery Hill to reach the A20 at Mottingham where its next junction would have been constructed.Next, heading west out of the London Borough of Greenwich, the motorway would have briefly crossed the northern tip of the London Borough of Bromley, via another group of playing fields before entering the London Borough of Lewisham to connect to the A2212 near Grove Park station.Here the route encounters the first substantial urban development cutting an alignment through the London County Council's Downham Estate – land already in public ownership, thereby avoiding the need for expensive land purchases and compensation payments.
