M4-M5 Link Tunnels
The M4-M5 Link is being delivered in two stages:
- Stage one - construction of the M4-M5 Link Tunnels between the New M4 at Haberfield and the New M5 at St Peters and stub tunnels to the Rozelle Interchange. This stage is being managed by Sydney Motorway Corporation.
- Stage two - construction of the Rozelle Interchange and Iron Cove Link. This stage is being managed by Roads and Maritime Services.
The M4-M5 Link Tunnels project is the final and most critical component of WestConnex, featuring twin tunnels between the New M4 at Haberfield and the New M5 at St Peters. Each tunnel will be approximately 7.5 kilometres long and able to accommodate up to four lanes of traffic in each direction. The M4-M5 Link Tunnels will be delivered as a stand-alone project, and provide an additional 2.5 hectares of green space in St Peters.
Environment and planning
The M4-M5 Link Tunnels received NSW planning approval in April 2018.

WestConnex is able to meet stringent air quality standards in the tunnels and the surrounding community using state-of-the-art ventilation and tunnel design. Filtration is not needed as it would not provide any measurable improvement to the air quality in the surrounding community.
We fully recognise the importance of Sydney Park and the investments that the City of Sydney Council and others have made in recent years.
A strip of land owned by Roads and Maritime Services adjacent to Sydney Park is being used to widen Euston Road as part of local road upgrades. This is not part of Sydney Park.
As outlined in the City of Sydney’s own management plan for Sydney Park, this land is dedicated road space and has been subject to a long-standing road widening reservation.
A small boundary strip, adjacent to the road reserve, is also required for the local road widening, however this is more than offset by the additional 8.5 hectares of open green space being created at St Peters Interchange.
Two hectares of this open green space will be directly connected to Sydney Park via a land bridge over Campbell Road.
Community or social cohesion programs will be implemented to enhance the cohesion in precincts directly affected by WestConnex. Initiatives may include enhancement of open space, accessibility of public areas, active community involvement and engagement, support of community initiatives and provision of grants to eligible groups in the local community.
