Another Crossrail tunnel has been completed in east London.
Tunnel boring machine Jessica completed the drive from Limmo Peninsula, near Canning Town, into Victoria Dock Portal.
TBM tunnelling on the £14bn scheme is due to complete early next year. Crossrail services are due to begin taking passengers through central London in 2018.
The 1,000 tonne Jessica machine, named after Olympic gold medallist Jessica Ennis-Hill, created its latest 900m journey in just nine weeks.
It was the machine’s second Crossrail tunnel drive, after iforming the spur from Pudding Mill Lane near Stratford to Stepney Green.
Crossrail chief executive Andrew Wolstenholme said: “We continue to make good progress on Crossrail’s tunnels.
“The end is now in sight on Crossrail’s tunneling marathon, but there is much more to do in the form of installing railway systems and fitting out the stations.”
Joint venture Dragados Sisk is constructing the eastern tunnels between Pudding Mill Lane and Stepney Green; Limmo Peninsula and Farringdon; and Victoria Dock Portal and Limmo.
The government last week mooted an extension of Crossrail into Hertfordshire.
