Open to motorists and connecting Sydney like never before!
The Rozelle Interchange opened to traffic in the early hours of Sunday, 26 November 2023, subsequently marking the completion of WestConnex. This newly built and intricate web of tunnels connects motorists to:
- M4 and M8 tunnel extensions,
- Anzac Bridge,
- City West Link,
- Western Distributor,
- a toll-free underground bypass of Victoria Road, and
- the future Western Harbour Tunnel.
Joint Venture partners John Holland and CPB Contractors can claim a stake in building one of the world’s most complicated underground interchanges.
About 20,000 construction workers were involved in the project over four years. Working 24/7 the team constructed 24 kilometres of tunnels, sprawling across four layers. Moreover, these record-breaking tunnels range from average depths between 35 metres to 65 metres.
Consisting of an extremely impressive 12 bridges and two ventilation facilities, the project also delivers up to 10 hectares of parklands. Not only is the interchange connecting some of Sydney’s busiest commuter corridors, but the new Rozelle Parklands also delivers a host of community benefits. Built structures contribute a boardwalk and bush trails through wetland areas, a fitness trail and play equipment.
The interchange provides faster access to the CBD and the inner-west for millions of people. Around 100,000 vehicles are expected to use the Rozelle Interchange per day. Finally, its completion marks the end of the WestConnex project that commenced in 2015 with the new M4 tunnel.
The Rozelle Interchange is part of the $16.8 billion WestConnex Project. It was jointly funded, with $1.5 billion from the Australian Government, and a $2 billion concessional loan, and with the NSW Government contributing $1.8 billion.
