The JV will now work with Transurban and the Victorian Government through an Environment Effects Statement (EES) process, which will assess the potential environmental, social, economic and planning impacts of the project, and recommend the approach to manage these impacts.
The AUD$5.5bn ($4.2bn) project will include the widening of the West Gate Freeway from eight lanes to 12 between the M80 Ring Road and Williamstown Road, and the construction of a 2.8km eastbound tunnel and 4km westbound tunnel under Yarraville.
It will also involve the construction of a new bridge over the Maribyrnong River providing an alternative to the West Gate Bridge, an elevated road along Footscray Road to the Port of Melbourne, CityLink and the city’s north, and major new cycling and pedestrian paths.
Román Garrido, CPB Contractors’ managing director, said: “CPB Contractors’ major projects and tunnelling capabilities will ensure an efficient and effective works program is put in place to minimise disruption and maximise safety for road users during the construction period.
“Our team is focused on ensuring opportunities for local workers and businesses, providing a strategic and socially-inclusive procurement program, and value for money urban designs that deliver enhanced benefits to communities and stakeholders.”
John Holland executive general manager VIC, Trevor Hall, said: “The West Gate Tunnel Project will provide an alternative route to the West Gate Bridge and direct access to the port. In doing so, it will slash traffic congestion, improve productivity, remove numerous trucks from local roads and reduce travel times for motorists.”
Contract close is expected in late 2017. Subject to planning approvals, construction work is expected to start in 2018.
The project is scheduled to open to traffic in 2022.
