Warringah Freeway Upgrade

Warringah Freeway Upgrade

The Warringah Freeway Upgrade will upgrade four-kilometres of the Warringah Freeway, between High Street at North Sydney and Willoughby Road at Naremburn providing a link between the future Beaches Link and Western Harbour Tunnel. Once complete, the three projects will provide a continuous connection from WestConnex at Rozelle to Sydney’s Northern Beaches. 

The Warringah Freeway Upgrade will include: 

  • upgrades to interchanges at Falcon Street in Cammeray and High Street in North Sydney
  • relocation of road and shared user bridges across the Warringah Freeway
  • connection of the Warringah Freeway to the portals for the Western Harbour Tunnel mainline tunnels and the Beaches Link tunnels via on- and off-ramps
  • new and upgraded pedestrian and cyclist infrastructure
  • upgrades and modifications to bus infrastructure, and
  • other operational infrastructure, including surface drainage and utility infrastructure, signage, tolling, lighting, CCTV and other traffic management systems.

Many of the funding announcements to date refer collectively to the Warringah Freeway Upgrade, Northern Beaches Tunnel and Western Harbour Tunnel.
