Sydney Metro Northwest: Surface Works, Viaducts & Civils

Sydney Metro Northwest, formerly known as the North West Rail Link, is the first stage of Sydney Metro, Australia’s largest public transport project. The project is being delivered in three major contracts: Tunnels and Station Civil Works; Surface and Viaduct Civil Works; and Operations, Trains and Systems.

We are a member of the Impregilo-Salini Joint Venture, which have been awarded the Surface and Viaduct Civil (SVC) Works contract.

The SVC contract includes the construction of a 4 km elevated skytrain viaduct between Bella Vista and Rouse Hill in Sydney’s north-west. The skytrain will be between 10 m and 13 m above ground level, supported by 130 concrete piers, spaced approximately 39 m apart.

The other major component of the project is a 270 m long, 45 m high cable-stayed bridge over Windsor Road at Rouse Hill. We designed the cable-stayed bridge which includes two pylons and a single plane of cables in a modified fan arrangement, supported by 32 steel cables.

The skytrain viaduct and bridge are part of the 36 km rail link between Rouse Hill and Chatswood.

Sydney Metro Northwest will deliver eight new railway stations and 4,000 commuter car parking spaces to Sydney’s growing North West.

We have been engaged as lead Designer to provide design of the permanent structures and civil works, including:

  • Viaduct and station platforms
  • Viaduct crossings over major roadways
  • All bulk earthwork requirements associated with cut, fill and embankments roadwork design for Windsor Road and Balmoral Road
  • The adjustment of existing infrastructure impacted by the works
