The Western Harbour Tunnel and the Warringah Freeway Upgrade reached a significant milestone today, with a massive 95-tonne road header breaking through the final layer of rock, linking these two major NSW infrastructure projects for the first time.

This landmark achievement, part of the Western Harbour Tunnel Stage 2, involved removing around 1,000,000 tonnes of rock—equivalent to nearly 7,000 blue whales or 200,000 school buses—marking a critical step towards completion.
Major Boost to Sydney Traffic Flow
Scheduled to open in 2028, the 6.5-kilometre Western Harbour Tunnel is the first new road harbour crossing constructed in nearly three decades and will remain publicly owned. This tunnel aims to significantly ease congestion on major routes including the Sydney Harbour Bridge, Harbour Tunnel, Anzac Bridge, and Western Distributor.
Upon completion, drivers are expected to see considerable reductions in travel times:
- Up to 20 minutes saved between Sydney Olympic Park and North Sydney
- Up to 20 minutes saved between Leichhardt and North Sydney
- Up to 15 minutes saved from North Sydney to Sydney Kingsford Smith Airport
Additionally, traffic reductions will be substantial:
- 35% reduction on the Western Distributor
- 20% reduction in Sydney Harbour Tunnel
- 17% reduction on the Sydney Harbour Bridge

Extensive Improvements with Warringah Freeway Upgrade
The Warringah Freeway Upgrade, currently over 70% complete and set to finish in late 2026, has been instrumental in preparing Australia's busiest roads to integrate smoothly with the Western Harbour Tunnel. Key enhancements include:
- Over 120,200 significant traffic switches during construction
- Improved pedestrian and cyclist connections via four new bridges
- Streamlined lanes for safer, simpler CBD access
- Dedicated bus lane enhancing reliability for commuters
Later this year, two giant tunnel boring machines will commence construction of twin, three-lane tunnels beneath Sydney Harbour, linking Birchgrove and Waverton.
Economic and Employment Benefits
These infrastructure developments are anticipated to support approximately 7,500 full-time equivalent jobs throughout their construction, significantly boosting the local economy.

Statements from Officials
Premier Chris Minns:
"Today's breakthrough literally shines a light at the end of the Western Harbour Tunnel, marking a pivotal moment in enhancing Sydney's transport infrastructure. These projects will transform commuting for thousands, improving reliability and drastically cutting travel times."
Roads Minister Jenny Aitchison:
"Upgrading one of Australia's busiest road networks while keeping traffic moving smoothly is like performing open-heart surgery during a marathon. This remarkable achievement underscores our commitment to strategic infrastructure improvements, benefiting drivers, bus passengers, and the broader community long into the future."
The NSW Government extends its gratitude to the local communities and commuters for their continued patience and cooperation during these significant infrastructure enhancements.
