Beaches Link

Detailed Planning
Beaches Link

The Beaches Link is a proposed tunnel linking the Northern Beaches to the Warringah Freeway in North Sydney.

The future Western Harbour Tunnel will also connect with the Warringah Freeway, allowing motorists to travel on a single roadway from the Northern Beaches, through the Western Harbour Tunnel and into the WestConnex roadways system.

Detailed Designs in the Project Update indicate Beaches Link will include over 11 kilometres of tunnels as well as around five kilometres of surface road upgrades. The main tunnel between Cammeray, connecting to the Western Harbour Tunnel, and Balgowlah will be three lanes each way, with connections to Wakehurst Parkway and Gore Hill Freeway two lanes each way. The preferred method for constructing the tunnels involves using multiple road header machines, with the section under Middle Harbour to use immersed tube tunnels.

Three kilometres of Wakehurst Parkway to the Northern Beaches Hospital will be upgraded along with further surface works to integrate the tunnels with the existing road network.
