Jubilee Line Extension - Contract 110

Shortlisted schemes Major Projects

Perhaps the most curious thing about the magnificent new station at North Greenwich is that no one has made the effort to change its name.

North Greenwich was well on the way to being finished even before the decision was made to site the Dome right next door. Had the station name been immediately changed to 'The Dome' or 'Millennium Exhibition' the world, and especially the media, would know that at least this part of the troubled Jubilee Line Extension has been open to business for several months and is all ready for the big event. And the station would have been discovered to be a revolution for the Tube - having more in common with a set from Star Wars than the rabbit warren tunnels which make up some of the older parts of London's Underground.

As well as being the first of the JLE's 'open box' construction stations to handle passengers, it is also by far the biggest, set in a cofferdam some 400m long 30m wide and 25m deep in highly contaminated ground.

Just for good measure Contract 110 includes four separate running tunnels crossing beneath the Thames. These were driven through ground that was occasionally straightforward but mostly very difficult.
