The Northern Road upgrade, Glenmore Parkway to Jamison Road

The Australian and NSW governments are upgrading The Northern Road as part of the Western Sydney Infrastructure Plan (WSIP), a $3.6 billion road investment program.

The Northern Road upgrade will 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.

This upgrade covers about 4 kilometres between Glenmore Parkway, Glenmore Park and Jamison Road, South Penrith. It is planned to generally follow the existing road alignment.

Updates and announcements

Night work and closures at The Northern Road and M4 Motorway interchange will continue in October and November 2018, weather permitting.

This work is necessary to prepare The Northern Road bridge at South Penrith for opening later this year. Work includes earthworks, constructing drainage and road pavement, asphalting, relocating street lights, installing and adjusting temporary barriers and signage and line marking. More information about the night work can be viewed in the notifications below.

We may close roads and divert traffic while we carry out this work, so please be aware of road changes and follow the directions of signs and traffic control. And thank you for your patience!

Night work

To minimise impact on traffic and safety of the travelling public, some work will need to take place at night.

Night work and closures at The Northern Road and M4 Motorway interchange will continue in October and November 2018, weather permitting.

Our normal work hours will be between 7am and 6pm on Monday to Friday, and 8am to 1pm on Saturday.

Cyclist detour

For safety reasons, there will no cyclist access on The Northern Road between Glenmore Parkway and Jamison Road and along the M4 Motorway between Kent Road and Mulgoa Road from Monday, 4 September 2017 until project completion in 2020. Please view or download our detour map (PDF, 1.15Mb)

Changed traffic conditions

The speed limit on the M4 Motorway between Kent Road, Claremont Meadows and Mulgoa Road, Jamisontown will be reduced to 80km/h, 24 hours a day seven days a week from Friday, 8 September 2017.

The speed limit on Glenmore Parkway between The Northern Road and Windorra Avenue will be reduced to 40km/h, 24 hours a day seven days a week from Monday 16 October 2017 until roundabout completion in mid-2018

Operating hours for the site office

To carry out The Northern Road upgrade, a site office has been established at the corner of Wentworth Road and The Northern Road, Orchard Hills.

The site office will operate 24 hours a day, seven days a week from Friday, 28 July 2017 until the project’s completion in 2020. The site will be used for general purposes including as an office, for parking and to store materials.

Please view or download our operating hours letter (PDF, 238Kb) for more information.

The benefits of The Northern Road upgrade:

  • Improving travel times by:
    • Increasing the number of lanes along The Northern Road
    • Removing a set of traffic lights at the M4 Interchange
    • Providing additional turning lanes at some intersections
  • Allowing for reliable public transport by providing a continuous kerbside bus lane in each direction
  • Improving safety for pedestrians and cyclists by providing a new shared path
  • Improving connectivity for pedestrians by providing new footpaths
  • Improving road safety by:
    • Providing a central median to separate opposing traffic flows
    • Installing new traffic lights at two existing intersections
    • Providing separate turning lanes at some intersections
    • Improving the alignment of the road
  • Improving local access by providing an extension of Cross Road to Wentworth Road
  • Mitigating traffic noise impacts by providing two new noise barriers.

Key features

Key features of The Northern Road upgrade include:

  • Widening The Northern Road to provide four lanes in each direction (three general traffic lanes and a kerbside bus lane)
  • Building a new bridge over the M4 Motorway with the existing bridge to be removed
  • Installing new traffic lights and turning lanes at some intersections
  • Providing continuous bus lanes in each direction
  • Installing a central median
  • Providing a new shared pedestrian and cyclist path and footpaths
  • Installing new street lighting, drainage, safety barriers and landscaping
  • Installing new retaining walls
  • Installing two new noise barriers

What happens next?

We have awarded the design and construction contract to Lendlease. Work started in mid-2017 and it is expected that the road will be open to traffic by 2020.

We will continue to provide updates to the community as the project progresses.

Community involvement
