Breakthrough of a tunnel boring machine (TBM) at Whitechapel station marks completion of 75% of the tunnels on Crossrail with 32km of the tunnels now completed.
Workers on the Crossrail C305 Limmo to Farringdon tunnel drive celebrated the arrival of the Herrenknecht TBM –named Victoria after Queen Victoria – at the end of last week.
The TBM was launched by a joint venture of Dragados and Sisk from the Limmo Peninsula at the end of 2012 and is now expected to undergo maintenance before being relaunched for the final part of the 8.3km drive to Farringdon.
“With three quarters of tunnelling complete, we’re tantalisingly close to finishing what is without doubt a monumental feat of engineering,” said Mayor of London Boris Johnson. “It’s quite remarkable what the Crossrail team has achieved so far and we now look forward to the next exciting stage of the project - the fitting out of the Crossrail stations of the future.”
