Need for design to                  New crossings for fauna provided along the Wakehurst Parkway

    What we heard                        How the design addresses this

    Preference for tunnel ramps and      Proposed tunnel alignment changed so tunnel ramps are located in
    construction to use Balgowlah        the centre of Burnt Bridge Creek Deviation

22   Beaches Link – Project update
This section of the project update
provides information about the
proposed reference design for an
integrated transport solution that
includes Beaches Link and the
Gore Hill Freeway connection.
Most of this project will be deep
underground in tunnels.
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.
Roads and Maritime 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 will be 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 Beaches Link tunnel.
The depths, shown in metres, are measured from ground level to the road surface in the tunnel.
