M4-M5 Link Tunnels
The M4-M5 Link Tunnels is the first stage of the M4-M5 Link which 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 WestConnex.
- Stage two - construction of the Rozelle Interchange and Iron Cove Link. This stage is being managed by Transport for New South Wales.
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.

Legacy is defined as ‘delivering sustainable and lasting benefits to the local economy, community and natural environment’. Legacy projects will be identified and developed in consultation with the community, local councils and community groups.
The planning approval to construct each stage of WestConnex includes conditions to incorporate and deliver social and environmental outcomes including the requirement for an Urban Design and Landscaping Plan, a Social Cohesion Plan, and a Residual Land Management Plan.
In 2013, King Street was identified in the Sydney Clearways Strategy for further investigation of possible extended weekday and weekend clearways, based on an assessment of traffic volumes and travel speeds at that time.
It is understood that when the M4-M5 Link is complete in 2023, daily weekday traffic volumes are forecast to decrease on King Street with 4000 vehicles removed (compared to without the project).
As a result, there are no plans to change the existing clearways on King Street, Newtown, at this time.
Roads and Maritime has not carried out further investigations for clearways on King Street at Newtown.Offers
