The Northern Road upgrade, The Old Northern Road to Peter Brock Drive

The Australian and NSW governments are upgrading The Northern Road as part of the Western Sydney Infrastructure Plan (WSIP), a 10 year, $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 of Western Sydney Airport. It would also improve safety, increase road capacity and reduce congestion and travel times in the future.

The upgrade is being delivered in stages. This first stage covers 3.3 kilometres between The Old Northern Road, Narellan and Peter Brock Drive, Oran Park.

Updates and announcements

The Minister for Urban Infrastructure and Cities, Paul Fletcher, the Minister for Roads, Maritime and Freight, Melinda Pavey and the Member for Camden, Chris Patterson officially opened The Northern Road between The Old Northern Road, Narellan and Peter Brock Drive, Oran Park, on Wednesday 4 April, 2018. We thank the community for their patience as we delivered this vital upgrade.

From May 2018, for a period of up to 32 weeks, the project team will be preparing and constructing noise walls on the eastern side of The Northern Road between Old Northern Road and 400 m north of Hillside Drive, Harrington Park.

  • Funding: Australian and NSW governments

Project background

This stage of The Northern Road upgrade is 3.3 kilometres between The Old Northern Road, Narellan and Peter Brock Drive, Oran Park. The Northern Road will be one of the main arterial transport corridors in Sydney’s South West Priority Growth Area. As residential and commercial development occurs, the amount of traffic in the area is expected to increase on The Northern Road. The Northern Road upgrade will also support Western Sydney Airport.. The Northern Road between Camden Valley Way and The Old Northern Road was upgraded in 2007.

There are four intersections along the route. Three of these intersections have traffic lights, to give access to existing and future residential and commercial precincts.

Benefits

The key benefits of the project are:

  • increased capacity to cater for future population growth in the area
  • improved safety for road users through:
    • new intersections with traffic lights to access precincts
    • a central median to separate opposing traffic flows
    • turning lanes at intersections
  • improved safety for cyclists and pedestrians through an off-road shared path
  • improved travel times and access to future precincts along The Northern Road
  • improved access and travel times for road freight in Sydney’s south west.

Key features

The key features of the project include:

  • widening The Northern Road to provide three lanes in each direction (two general traffic lanes and a kerbside bus lane)
  • an 80km/h speed limit
  • a three metre wide off-road shared pedestrian and cyclist path
  • designated turning lanes
  • three intersection upgrades with traffic lights at Porrende Street, Hillside Drive and Cobbity Road
  • two new bridges over Narellan Creek for northbound and southbound traffic
  • bicycle and pedestrian crossings at traffic lights.

What happens next?

Minor work including to be completed by mid-April 2018, weather permitting, includes:

  • landscaping
  • completion of footpath on side roads
  • final asphalting on Cobbitty Road and Fairwater Drive
  • pavement line marking , weather permitting.

 Two short sections of street lighting will be completed in mid-2018.  

Work on the noise walls will start mid-2018 and is due for completion in early 2019.
