Construction overview

There are a total of 16 construction sites for Sydney Metro Northwest.

Program of work

Depending on the site and stage of the project, any single construction site may have multiple functions over the life of the project. For example, a construction site can be used to excavate the future area for a station and later for the launch of a tunnel boring machine.

There are 16 work sites. From these 16 work sites, there were three overarching core work zones:

  • Epping to Bella Vista Station: tunnel work (now complete)
  • Bella Vista Station to Rouse Hill Station: embankment and skytrain
  • Rouse Hill Station to Tallawong Road: surface or bridge and viaduct structures, Metro Trains Facility.
