Another landmark has been reached on the £14bn Crossrail scheme.
Tunnel Boring Machine Ellie broke through into a cavern 40m beneath Stepney Green in East London, marking the structural completion of tunnels for the north east spur.
The spur will link Whitechapel and Pudding Mill Lane, and its tunnel has taken over three months for joint venture Dragados Sisk to create.
In the coming weeks the 1,000 tonne Ellie machine – named after Paralympic champion Ellie Simmonds – will be lifted out of the cavern and taken by road to Limmo Peninsula. From there it will be re-assembled ahead of its next job tunnelling towards Victoria Dock Portal.
Crossrail chief executive Andrew Wolstenholme said: “Ellie has made a safe journey from the shadow of the Olympic stadium to our site at Stepney Green.
“Our tunnel teams deserve congratulations for an impressive feat of engineering. Construction of the new rail tunnels for Europe’s largest infrastructure project is now over 80 per cent complete. Crossrail continues to be delivered on time and on budget.”
