Rizzani de Eccher Australia in joint venture with Leighton Contractors has been selected by WestConnex Delivery Authority (WDA) to design and build the M4 Widening, as part of the first stage of WestConnex, Australia’s biggest urban road project.
The M4 Widening will upgrade one of the busiest motorways in Sydney through an additional lane in each direction between Church Street, Parramatta and Homebush Bay Drive, Homebush which includes a new 1.8km long viaduct and two new viaducts on the ramps.
The project is scheduled to start early in 2015 and the new lanes are due to open to traffic in 2017.
