East Cross Route

East Cross Route (ECR) is a dual-carriageway road constructed in east London as part of the uncompleted Ringway 1 as part of the London Ringways plan drawn up the 1960s to create a series of high speed roads circling and radiating out from central London. The road was constructed between 1967 and 1973 and runs from Hackney Wick in north-east London, through the Blackwall Tunnel, to Kidbrooke in south-east London. The ECR was initially designated as part of the A102, but has, subsequently, been partially renumbered so that sections of it are now the A2 and A12.
