At the northern end of the ECR, the unrealised plans would have seen it connect at Hackney Wick to the unbuilt North Cross Route which would have run west across north London via Dalston, and also to the M11 motorway which was originally planned to continue south from its current starting point at the North Circular Road (A406) in South Woodford) to join Ringway 1. Part of this plan was eventually achieved in a modified form when, in the 1990s the 'A12 Hackney to M11 link road', or 'M11 Link Road' was constructed through Leyton, Leytonstone and Wanstead to connect to the ECR at Hackney Wick. This extension was designated as the A12 and required just the sort of controversial construction methods and widescale demolitions of residential areas that caused the 1960s schemes to be cancelled and provoked to the major M11 link road protest. After the new road was built, the northern part of the ECR became the A12.
