Updates and announcements

The Environmental Impact Statement (EIS) and concept design for The Northern Road upgrade between Mersey Road, Bringelly and Glenmore Parkway, Glenmore Park was on public exhibition from 21 June to 2 August 2017. 

The Australian Government Department of the Environment and Energy, NSW Department of Planning and Environment and Roads and Maritime Services are currently considering all submissions received during the exhibition of the Environmental Impact Statement, and a submissions report will be prepared.

The latest animation videocommunity update newsletter (PDF, 1.46Mb) and Frequently Asked Questions (PDF, 220Kb) provides more information on the proposed and the Environmental Impact Statement is available from the Department of Planning and Environment website.

Project background

The Northern Road upgrade would deliver new and upgraded roads to support integrated transport in the region and capitalise on the economic benefits from developing the Western Sydney Airport at Badgerys Creek. It would also improve safety, increase road capacity and reduce congestion and travel times in the future.

The Northern Road upgrade between Mersey Road, Bringelly, and Glenmore Parkway, Glenmore Park covers about 16 kilometres and would divert The Northern Road around the Western Sydney Airport site and around Luddenham town centre. The project is being planned between Mersey Road and Glenmore Parkway and will be delivered in three sections between:

  • Mersey Road and Eaton Road
  • Eaton Road to Littlefields Road
  • Littlefields Road to Glenmore Parkway.

Project benefits

The benefits of the proposed The Northern Road upgrade between Mersey Road, Bringelly and Glenmore Parkway, Glenmore Park include:

  • improved transport connections between Penrith, the M4 Motorway, the Western Sydney Airport and surrounding developments
  • increased road capacity for future growth and development
  • improved access for construction and operation of the Western Sydney Airport
  • improved public transport by providing dedicated bus lanes
  • improved safety for pedestrians and cyclists by providing a new shared path
  • improved safety for all road users by:
    • installing traffic lights at some intersections
    • building a central median to separate opposing traffic flows
    • providing turning lanes at some intersections
  • improved alignment of the road
  • improved street lighting
  • improved traffic efficiency for road users.

Key features

The key features of the project include:

  • a six-lane divided road between Mersey Road, Bringelly and Bradley Street, Glenmore Park (two general traffic lanes and a kerbside bus lane in each direction). A wide central median would allow for an extra travel lane in each direction in the future, if required
  • an eight-lane divided road between Bradley Street, Glenmore Park and just south of Glenmore Parkway, Glenmore Park (three general traffic lanes and a kerbside bus lane in each direction separated by a central median)
  • about eight kilometres of new road between Mersey Road, Bringelly and just south of the existing Elizabeth Drive, Luddenham to realign the section of The Northern Road that currently runs through the Western Sydney Airport site and to bypass the Luddenham town centre
  • about eight kilometres of upgraded and widened road between the existing Elizabeth Drive, Luddenham and just south of Glenmore Parkway, Glenmore Park
  • access to the Luddenham town centre from north of the realigned The Northern Road and the existing The Northern Road
  • four new traffic light intersections and new traffic lights at existing intersections
  • local road changes and upgrades to current access arrangements for businesses and private properties
  • a new shared path on the western side of The Northern Road and pedestrian paths on the eastern side of The Northern Road where required.

NSW Environmental Impact Statement/Draft Commonwealth Environmental Impact Statement

To meet the requirements of both the Commonwealth and State planning approval processes for the proposed upgrade, Roads and Maritime prepared a single document acting as both the NSW Environmental Impact Statement (EIS) and the Commonwealth Draft Environmental Impact Statement. The EIS document outlines the key features of the project and its potential environmental and social impact during construction and operation.

The NSW Department of Planning and Environment placed the EIS on public exhibition between 21 June and 2 August 2017. 

What happens next?

The Australian Government Department of the Environment and Energy, NSW Department of Planning and Environment and Roads and Maritime Services are currently considering all submissions received during the display of the concept design and Environmental Impact Statement.

Roads and Maritime will prepare a final EIS containing a submissions report (addressing both Commonwealth and NSW submissions) and a preferred infrastructure report, if necessary, to respond to the issues raised. This will be published and made available to the public.

An assessment report will be prepared by the NSW Department of Planning and Environment and a recommendation report will be prepared by the Australian Government Department of the Environment and Energy. Once these reports are finalised, the Commonwealth Environment Minister and the NSW Planning Minister will decide whether or not to approve the project, any modifications that must be made, and the conditions to be attached to any approval.

The community will continue to be updated as the project processes.
