Wynyard Walk

Sydney CBD, NSW

Currently under construction, Wynyard Walk is one of Sydney’s largest and most complex transport developments. It is a multi-stage build that will see a fully accessible pedestrian walkway in the centre of Sydney’s CBD, connecting the busy city train station at Wynyard to the developing CBD Western corridor and Barangaroo. The key features of the project include:

  • Western entry to Wynyard Station – a new Clarence Street Entry Building
  • Railway House transfer structure – a complex underpinning of an existing 12 level 1920’s heritage building in an extremely small space. This element required extensive high tech surveying monitoring systems and multi-stage jacking and supporting of the existing building
  • Margaret Street transfer – structural reconfiguration to provide for a tunnel adjacent to an existing 20 storey tower, and beneath the existing carpark
  • Western Portal – reconfiguration to the Napolean Plaza and new canopy structure
  • Sussex Street Pedestrian Bridge – connects Wynyard Walk to Barangaroo, where all architectural features are exposed
  • Pedestrian Tunnel – a new 120m long tunnel constructed below both Clarence and Margaret Street

The complexity of the project is continuing construction, while one of Sydney’s busiest train lines and major street networks remains open and completely operational.
