Inland Rail – Illabo to Stockinbingal (I2S)

Illabo to Stockinbingal, NSW

Project Description

Inland Rail is an important project to meet Australia’s growing freight task, improve road safety and help decarbonise our economy. Inland Rail involves enhancing approximately 1,000km of existing railway track and constructing 600km of new track passing through regional Victoria, New South Wales and Queensland.

The Illabo to Stockinbingal (I2S) project involves the construction of 37km of new rail corridor and
2km of upgraded track just east of Illabo and at Stockinbingal, NSW. This new section of rail corridor will provide a direct route from Illabo to Stockinbingal through to the existing Forbes line. This will bypass Cootamundra and the steep and windy Bethungra Range with its Bethungra Spiral.

Western Harbour Tunnel Stage 2

Sydney, NSW

Project Description

The Western Harbour Tunnel will be the crucial second road crossing underneath Sydney Harbour, providing a western bypass of the CBD with twin three-lane tunnels to ease pressure on the Sydney road network.

Stage 2 includes tunnelling from the WestConnex Rozelle Interchange at Birchgrove to the Warringah Freeway at Cammeray. The original plans for an immersed tube tunnel were changed to a TBM methodology, with twin 1.5km drives under Sydney Harbour, to reduce impacts on the harbour and seabed. The Stage 2 scope also includes roadheader tunnelling and full fit-out of the tunnels.
