The NSW Government is calling for expressions of interest to build a major section of the WestConnex M4-M5 Link, the Rozelle Interchange, which is described as one of the most complex parts of the M4-M5 Link, with most of the motorway to be located below the surface.
The M4-M5 Link is the third stage of WestConnex and involves tunnels connecting the New M4 at Haberfield to the New M5 at St Peters, with an interchange at Rozelle. The Rozelle Interchange will include:
- North-south tunnels connecting Victoria Road, the proposed Western Harbour Tunnel and the New M5 at St Peters;
- North-south tunnels connecting the main tunnels to City West Link;
- East-west tunnels connecting Haberfield and the ANZAC Bridge;
- Iron Cove Link connecting Victoria Road to the ANZAC Bridge; and
- Tunnel stubs and ramps that will connect to the proposed Western Harbour Tunnel and Beaches Link.
Sydney Motorway Corporation Chief Executive Officer Dennis Cliche said the complexity and scale of the project will require the world's best design and construction expertise.
"The Rozelle Interchange will be built at depths of up to 65 metres with multiple surface connections so we need industry to put forward the best possible design and construction solutions to deliver this vital part of Sydney's future road network", Mr Cliche said.
"The interchange design also allows us to create the single largest parcel of urban green space ever delivered by a road project in Australia's history, with the disused Rozelle Rail Yards to be transformed into 10 hectares of open space."
Sydney Motorway Corporation has received eight registrations of interest to design and construct the project, with expressions of interest to close on September 15.
Project Director Peter Jones said the Rozelle Interchange and Iron Cove Link was the second stage of the M4-M5 Link package of works with the twin tunnels from Haberfield to St Peters to be built separately.
"We separated the project into two stages to maximise efficiency and value for money throughout the procurement process for the design and construction contracts", Mr Jones said.
"We recently selected John Holland CPB Contractors joint venture and Lend Lease Samsung Bouygues joint venture as the shortlisted tenderers to deliver the main tunnel works with construction targeted to commence in 2018 and potentially opening to traffic in 2022.
"The interchange works package includes construction of the Rozelle Interchange and the Iron Cove Link, including the supporting green space with construction targeted to commence in 2019 and opening in 2023."
The approximate $16.8 billion, 33-kilometre WestConnex tollway is being delivered across a number of stages, with the overall project to extend from Parramatta to Sydney's CBD, Sydney Airport and the Port Botany precinct and the M5 in south-west Sydney, and carry an estimated 400,000 vehicles per day.
