Warringah Freeway Upgrade

Under Procurement
Warringah Freeway Upgrade

The Warringah Freeway Upgrade in North Sydney will provide the link between the future Northern Beaches Tunnel and the Western Harbour Tunnel. It will allow a motorist to travel on a single roadway from the Northern Beaches, through the Western Harbour Tunnel and into the WestConnex roadways system.

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

The Warringah Freeway Upgrade will extend from the northern end of the Sydney Harbour Bridge to Willoughby Road, and will optimise traffic flow, reducing the number of merge points along with introducing a southbound bus lane. The upgrade will also improve Ridge Street and Ernest Street bridges.
