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 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 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. 

Environment and planning 

The M4-M5 Link Tunnels received NSW planning approval in April 2018.

    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 2019. 

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

    For the current toll estimates, see WestConnex tolls.

    WestConnex 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.

    The WestConnex Community Connections Program includes the WestConnex Community Grant Scheme, which provides grants of up to $10,000 to local groups such as such as schools, sporting associations and social enterprises located in and around the WestConnex project area.

    Grant applications are assessed against guidelines, which consider areas including community legacy, connecting communities, building capacity and helping people.
