 Much of the Ringway, particularly the southern section where a new route was required, would have been placed in cuttings to mitigate disruption to local residents.The North Circular Road was to have been improved to motorway standard along its existing route with the designated motorway number set to be M15.In the years since the Ringways Plan was cancelled most of the route has been upgraded, some of it close to motorway standard, but this has been done in a piecemeal manner.
