Updates and announcements

Have your say

Roads and Maritime has developed a concept design and Environmental Impact Statement for The Northern Road Upgrade between Mersey Road, Bringelly and Glenmore Parkway, Glenmore Park. The Environmental Impact Statement is on display for comment from Wednesday 21 June until Wednesday 2 August 2017.

We have prepared an animation video, a community update newsletter (PDF, 1.46Mb) and Frequently Asked Questions (PDF, 220Kb) to explain the concept design and Environmental Impact Statement (EIS).

The Environmental Impact Statementis available to view online at the Department of Planning and Environment website or you can view the EIS in hard copy at venues listed under How to make a submission.

You are encouraged to make a formal submission to the Department of Planning and Environment. Submissions must be in writing and can be lodged through the DPE website or mail, please refer to How to make a submission for more details.

Information sessions

We will be hosting three community information drop in sessions, where the project team will be available to answer any questions about the EIS. A formal presentation will not be given, so please attend at any time on:

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.

What has changed?

The concept design includes a number of changes to the preliminary road design. These include:

  • moving the realigned The Northern Road slightly to the east to reduce property impact between the section just west of Dwyer Road and Vicar Park Lane
  • addition of a new set of traffic lights and a u-turn bay at the southern entry to the Western Sydney Airport
  • a new left in and left out turn from Eaton Road east to the realigned The Northern Road
  • moving the access road linking the existing Elizabeth Drive and realigned Elizabeth Drive further to the east
  • a new u-turn bay on the realigned Elizabeth Drive
  • realignment of the service road between the extended section of Littlefields Road and Gates Road
  • a proposed incident management facility on the south west corner of the intersection at the realigned The Northern Road and the realigned Elizabeth Drive
  • confirmed location for the at grade interchange of the proposed M12 Motorway and The Northern Road.

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 has prepared a single document which acts as both the NSW Environmental Impact Statement (EIS) and the Commonwealth Draft Environmental Impact Statement. The document describes the project, the potential impact and how this impact will be managed.

The display of the NSW EIS/Draft Commonwealth EIS is an opportunity for the community and stakeholders to review the materials and provide feedback on the proposed upgrade.

You can submit comments on the EIS to the NSW Department of Planning and Environment from 21 June until 2 August 2017.

How to make a submission

As part of the environmental assessment process, you are encouraged to make a formal submission to the Department of Planning and Environment (DPE). Submissions must be in writing and can be lodged through the DPE website or mailed by Wednesday 2 August 2017.

Online: To make an online submission, go to the DPE website. Select the search result for The Northern Road Upgrade – Glenmore Park to Bringelly (SSI 15_7127) and follow the instructions on how to lodge your feedback online.

What happens next?

At the completion of the EIS public exhibition period, the NSW Department of Planning and Environment and the Australian Department of the Environment and Energy provides Roads and Maritime with a copy of submissions or summary of issues raised.

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.
