Western Harbour Tunnel – Project update 5
Design changes led by community feedback
In March 2017, the NSW
Government released a project

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.

Western Harbour Tunnel – Project update 21Design and construction 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. Roads and Maritime wants to hear what you think about this proposed reference design. We will shortly commence community engagement on the design presented in this project update.

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.
