Western Harbour Tunnel and Warringah Freeway Upgrade
The Western Harbour Tunnel and Warringah Freeway Upgrade is a major transport infrastructure project that will make it easier, faster and safer to get around Sydney.
By creating a western bypass of the Sydney CBD, the Western Harbour Tunnel will take pressure off the Sydney Harbour Bridge, Sydney Harbour Tunnel, Anzac Bridge and Western Distributor corridors to improve transport capacity in and around Sydney Harbour.
The Western Harbour Tunnel and Warringah Freeway Upgrade projects are expected to support around 11,000 full-time equivalent jobs during construction.
We know Sydney traffic can be frustrating, especially in peak hour. The Western Harbour Tunnel and Warringah Freeway Upgrade will change the way you travel across Sydney Harbour. This project will get you to places faster by improving capacity and providing new direct routes and reliability on both sides of the harbour.
This much needed new crossing of Sydney Harbour will be a game changer for our city. You will save time on your journeys and enjoy more direct bus routes between the Inner West, Sydney and North Sydney, with seamless connections to the future Sydney Metro and Sydney Trains.
On 8 September 2023, the NSW Government confirmed the decision to cancel the Beaches Link project.
Transport for NSW will write to the Department of Planning and Environment to withdraw its State Significant Infrastructure Application for this project.
Transport will continue to carry out a road network review to assess what, if any, network improvements may be required in northern Sydney and other impacted areas to ensure a safe, efficient and reliable road network for motorists.
