Tunnelling contract awarded for Sydney Harbour link

24 Jan A contract worth AU$722m (£382m) has been awarded for the initial stage of tunnelling for the Western Harbour Tunnel in Sydney, Australia.

Construction will begin within months following the appointment of a joint venture between John Holland and Hochtief subsidiary CPB. The team will build about 1.7km of tunnels from Rozelle to Birchgrove. John Holland and CPB are currently delivering the Rozelle interchange as part of WestConnex, with the new Western Harbour Tunnel contract ensuring a seamless continuation of tunnelling work already under way. 

Premier Dominic Perrottet said: “This is a critical milestone which will support hundreds of jobs and ensure significant benefits for drivers, including improved travel times and reduced congestion. The tunnel will not only revolutionise how we get around Sydney but also take the pressure off other major roads including the Sydney Harbour Bridge, Sydney Harbour Tunnel, Anzac Bridge and Western Distributor.”

The Western Harbour Tunnel will link WestConnex at Rozelle with the Warringah Freeway at North Sydney via 6.5km of tunnels under Sydney Harbour, with three lanes in each direction.

Member for North Shore Felicity Wilson said that early works, including geotechnical investigations into the detailed tunnel design, will start this month. “Major construction will begin in the middle of this year and I know drivers can’t wait to reap the rewards of this much-needed additional harbour crossing,” she said.
