Sydney Advances in Major Road Harbour Crossing Project
Completion of rock clearance marks a significant milestone for the Western Harbour Tunnel and Warringah Freeway upgrade.
Sydney is progressing towards the completion of its first new road harbour crossing in nearly thirty years, with the recent clearance of approximately one million tonnes of rock.
This development connects the Western Harbour Tunnel project with the Warringah Freeway upgrade, marking a pivotal moment since construction of the 6.5-kilometre freeway commenced in mid-2021.
The Western Harbour Tunnel aims to link the Warringah Freeway to the WestConnex M4 and M8 at the Rozelle Interchange.
The project is designed to alleviate congestion on major thoroughfares, including the Sydney Harbour Bridge, Harbour Tunnel, Anzac Bridge, and Western Distributor, all vital routes within one of Australia's busiest urban environments.
Traffic studies indicate that the tunnel is expected to reduce travel time for motorists by up to 20 minutes and decrease traffic volumes by as much as 35 percent.
Premier Chris Minns highlighted this achievement, describing it as a significant milestone that will enhance the movement of people across the city.
He remarked on the moment’s importance by stating, "For the first time, there is light at this end of the Western Harbour Tunnel — literally."
Roads Minister Jenny Aitchison emphasized the complexity of these infrastructure upgrades, comparing the challenges of construction to "doing open heart surgery while trying to run a marathon," given that work is being carried out alongside active traffic conditions.
The construction process now includes the development of two three-lane tunnels under the Sydney Harbour, connecting existing tunnels at Birchgrove with Waverton while the Warringah Freeway upgrade concurrently progresses.
This freeway enhancement involves the construction of new bridges, ramps, underpasses, and a dedicated bus lane leading into the Central Business District.
As of now, the Warringah Freeway upgrade is reported to be over 70 percent complete, with an anticipated completion date set for late 2026. However, the opening of the Western Harbour Tunnel is expected to take place in 2028. Upon its completion, the tunnel will serve as Sydney's third road harbour crossing.
