The construction cost of Australia’s West Gate Tunnel project may climb even higher according to reports. The project was previously estimated to cost up to US$4.93 billion (A$6.7 billion) to complete. However the work may now cost as much as US$2.43-3.83 billion (A$3.3-5.2 billion) extra to carry out.

The massive spike in costs arises from the discovery of around 3 million tonnes of contaminated ground along the route. The ground in question is contaminated with carcinogenic chemicals that will have to be disposed of safely.
