M4-M5 Link Tunnels

(Haberfield to St Peters)

Also referred to as M4-M5 Link Mainline Tunnels.

Tunnels connecting the New M4 at Haberfield and the New M5 at St Peters. 

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.

    Sydney Motorway Corporation is committed to making a meaningful and long term contribution to the communities in which it operates by investing in community-focussed programs during construction of WestConnex.

    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.

    WestConnex has a distance-based tolling system, like the existing M7 Motorway. Motorists pay only for the sections of the motorway they use and a maximum cap applies.

    Tolls will be introduced as each section of WestConnex opens to traffic. The new M4 opened to traffic in July 2017, and distance-based tolls commenced in August 2017. 

    Distance based tolling will begin on the M5 East and the New M5 when the New M5 opens to traffic in early 2020.

    Cars will pay one third of the heavy truck toll, reflecting the greater wear and tear trucks have on the motorway (an approach that is consistent with other Sydney motorways).

    For the current toll estimates, see WestConnex tolls.

     

    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.
