Western Harbour Tunnel – Project update 5 Design changes led by community feedback

In March 2017, the NSW Government released a project concept and started detailed design work on the Western Harbour Tunnel project.

Since then, there has been extensive community engagement, geotechnical testing, field studies and market sounding with the finance and construction industries. This project update provides an overview of how the proposed design has evolved, incorporating feedback from community and stakeholder groups over the past year. Roads and Maritime Services want to hear what you think about where we are up to. We will shortly commence community engagement on the design presented in this project update. Once we have heard your feedback, we will continue to refine the design. The NSW Government will then progress Aerial view of Birchgrove this refined design through the planning assessment process. This will include the exhibition of Environmental Impact Statements (EISs) when the community can What we heard How the design addresses this provide formal feedback. Do not use Birchgrove Oval for No proposal to use Birchgrove construction purposes Oval for construction

What we’ve heard Keep heavy construction traffic No tunnel spoil transport Extensive engagement has off the streets of Balmain and through Balmain or Birchgrove Birchgrove local streets included over 5000 face- to-face conversations via Water transport to be used wherever possible a series of 16 community feedback sessions, 12 shopping centre Concerns about air quality and Ventilation facility will be the proposed location of a located at the planned Rozelle displays, workshops and ventilation facility in Rozelle Interchange meetings with schools and Air quality has been assessed community groups. as part of the WestConnex M4-M5 Link EIS and is also We have made significant being addressed in the Western changes to the design Harbour Tunnel environmental based on what we assessment have heard from the No additional facilities required community. for the Western Harbour Tunnel in the Inner West

22 Western Harbour Tunnel – Project update This project update provides information about the proposed reference design for an integrated transport solution that includes Western Harbour Tunnel and the Warringah Freeway Upgrade. Most of Western Harbour Tunnel will be deep underground. Community and stakeholder input over the last year has resulted in significant design changes to the project.

Most of the project will be deep underground in tunnels. This greatly reduces surface impacts, including to private property, communities and the environment.

The tunnels, built mostly through high-quality Sydney sandstone, will be engineered and constructed by industry leaders using world-class technology, and world’s best practice in terms of safety, efficiency and road user experience. The vertical alignment diagrams show the approximate depth of the tunnels below the surface along the alignment of the Western Harbour Tunnel. The depths, shown in metres, are measured from ground level to the road surface in the tunnel.
