Westlink M7 Widening

Transport for NSW is proposing to widen the Westlink M7 by adding an extra lane each way within the existing median between the M5 interchange at Prestons to Richmond Road, Oakhurst/Glendenning. Widening the Westlink M7 would improve journey times for freight and motorists and support the future M12 Motorway and the Western Sydney International (Nancy-Bird Walton) Airport.

Project information

Transport for NSW is proposing to widen the Westlink M7 within the existing median by adding one lane in each direction between the M5 interchange at Prestons, approximately 140 metres south of the Kurrajong Road overhead bridge (southern end), to the Westlink M7 bridge at Richmond Road in Oakhurst/Glendenning (northern end). Once complete, there will be three lanes of traffic in each direction. The widening would not occur through the Light Horse Interchange at the M4 Motorway.

By increasing capacity and easing congestion, the widening would improve journey times for freight and motorists and alleviate pressure on some of our city’s most critical transport corridors. Increased capacity on the Westlink M7 would also support the future Western Sydney Aerotropolis and surrounding growth areas.

Benefits of widening the Westlink M7:

  • Ease congestion by enabling faster and more reliable connections between Sydney’s South West and North West
  • Better and more reliable trips for people, businesses, and freight
  • Improve journey times to planned growth areas and the new Western Sydney International (Nancy-Bird Walton) Airport.

The Modification Report was exhibited by the NSW Department of Planning and Environment for 21 days from Wednesday 3 August to Tuesday 23 August 2022. The Modification Report can still be viewed via the Department of Planning and Environment portal.

Transport has prepared a Submissions Report responding to community and stakeholder feedback received during the exhibition.

The Submissions Report can be viewed here.

During the exhibition period, we received 32 submissions from residents and stakeholders.

The main issues raised related to:

  • noise
  • traffic during construction
  • shared path impacts during construction.

The Submissions Report will help the NSW Department of Planning and Environment determine the modification application.

The Department of Planning and Environment would prepare the Secretary’s Environmental Assessment Report and provide it to the Minister for Planning, who would then decide whether to approve the project.

We will keep the community informed during the environmental assessment and approval process. Should the proposal be approved, construction is expected to start in 2023.
