Leighton Contractors, a Leighton Holdings company, in a joint venture with Rizzani de Eccher Australia has secured a contract from the WestConnex Delivery Authority (WDA) to design and construct the M4 Widening project.
Under the contract, joint venture will upgrade 7.5km of the M4 motorway in Sydney as part of the first stage of WestConnex, which is claimed to be Australia's biggest urban road project. Leighton Contractors' share of the contract is valued at about $150m.
The scope of the project includes widening the M4 from three to four lanes in each direction for approximately 7.5km between Church Street, Parramatta and Homebush Bay Drive, Homebush.
The project also includes widening the Granville viaduct and existing bridges, as well as constructing new access ramps and one new bridge.
The M4 Widening will connect with the future M4 East tunnel to Haberfield, also to be constructed as part of WestConnex Stage 1.
Marcelino Fernández Verdes, executive chairman and CEO of Leighton Holdings, said: "Australia is in the process of upgrading its road infrastructure and investing in new projects to ease congestion on heavily trafficked roads.
"With strong levels of investment in projects such as WestConnex, transport infrastructure will continue to be a significant market for the Leighton Group."
Major work is set to commence in early 2015 and the project is scheduled to open to traffic in 2017.
