Work underway on Crossrail tunnel portal
Construction work on the Crossrail tunnel entrance at Victoria Dock is underway after 420 metres of DLR track was moved.
The first part of the structure, known as Victoria Dock Portal, should be complete by 2014 and that summer a tunnel boring machine will be launched from the nearby Limmo Peninsula.
Towards the end of the year it will break through to the site. The portal will be completely finished the following year well ahead of the start of Crossrail services in 2018.
Bill Tucker, Crossrail's director for the central area, said: "The Victoria Dock Portal will be a key part of the Crossrail route, forming a gateway from the existing surface railway in east London into the new tunnels being built beneath central London.
"The start of construction at Victoria Dock is an important further step towards delivering lasting transport improvements for east London."
Workers will now drive 700 piles into the ground for the foundations at the site next to Custom House DLR.
Vinci Construction is carrying out the works on the portal.
Crossrail has also released video footage in timelapse of the work on the DLR tracks over Christmas.
