The Lendlease-led Melbourne Metro Rail consortium halted tunnelling work on the $11 billion project on Monday without notice to the Victorian government, after weeks of talks about cost blowouts reported to be as high as $3 billion.
While tunnelling work regularly stops for maintenance of the giant machines boring the twin 9 kilometre rail tunnels from Kensington to South Yarra, Monday's halt was unusual because the Cross Yarra Partnership communicated nothing ahead of the shutdown, The Australian Financial Review understands.
