Two years after large sinkholes opened above the construction of a $3.1bn Sydney motorway tunnel, the consortium charged with the project’s completion has been issued a notice forcing it to continue the job or face possible legal consequences.
The New South Wales roads minister, Jenny Aitchison, said contractor CGU had on Monday been issued a “notice of default”, forcing it to recommence work on the 90% complete M6 tunnel by 1 May.
