Crossrail has started work on the last east London tunnel, which is in close proximity to the London Underground Jubilee line, Docklands Light Railway, River Thames and River Lea.
The tunnel drive will begin from Limmo Peninsula, near Canning Town, and runs up to Victoria Dock Portal in east London.
This tunnelling will complete on Crossrail’s south-east spur, which stretches from Stepney Green to Abbey Wood.
Crossrail chief executive Andrew Wolstenholme said: "Huge amounts of planning go into every tunnel drive and this one is no different.
"We are deploying some of the world’s best engineering talent and machinery to safely build these new tunnels."
The tunnel projects of Crossrail, which are already 83% complete, will be finished next year once the tunnel machines reach Farringdon.
The Crossrail route will serve 40 stations and run from Reading and Heathrow Airport in the west, through new twin-bore tunnels below central London to Shenfield and Abbey Wood in the east. Services are scheduled to begin in 2018.
When fully operational in 2019, Crossrail will increase London’s rail-based transport capacity by 10%, support regeneration, reduce journey times and bring an extra 1.5 million people to within 45 minutes of central London.
Crossrail is jointly sponsored by the UK Department for Transport (DoT) and Transport for London (TfL).
