The Sydney Metro Northwest is Australia’s largest public transport project.

The Sydney Metro Northwest project involved the construction of a new metropolitan train line north-west of Sydney, connecting Chatswood station with Cudgegong Road.
The works in the section between Bella Vista station and Cudgegong Road, involved the design and construction of the "Skytrain" bridge and other civil works that made up one of the main sections of the line. 

The project involved building 8 new stations and 4,000 parking spaces. It is the first completely automated high-speed train system in the continent.

This is the biggest public transport infrastructure project currently under way in Australia, and the biggest in Sydney since Harbour Bridge was built almost 100 years ago.


Accolades: For Sydney's metro, the Infrastructure Sustainability Council of Australia (ISCA) awarded Salini Impregilo the best rating, placing the project among the World-Class Best Practice in Sustainability.  ISCA, a public-private non profit body, manages Australia's sole rating system, for assessing sustainability of infrastructure projects, from an environmental, social, economic and governance perspective. 

In particular, the Group received two awards, both for design – Leading IS Design rating – in 2015, and for building – Leading As Built IS rating – in 2017.
