The Northern Road Upgrade involved the construction of road works, bridge works and associated activities to upgrade 3.3km of The Northern Road (MR154) between Old Northern Road, Narellan and Peter Brock Drive, Oran Park in NSW.

The $57 million upgrade involved the conversion of the existing single carriageway road to a two-lane dual carriageway with dedicated bus lanes and the provision of the traffic signals at the intersections with Porrende Street/Fairwater Drive, Hillside Drive and Cobbitty Road West.

The project also included the construction of two new 46.5-metre long three-span bridges over Narellan Creek for the northbound and southbound carriageways and demolition of the existing bridge, earthworks, drainage, pavement and miscellaneous works including kerbs and/or gutters, concrete paving, safety street lighting, markings and landscaping.

Extensive utility adjustments were involved in the works including electrical, watermain, gas and communications.

The project was funded by the Australian and NSW governments and is part of the Western Sydney Infrastructure Plan, a 10-year road investment program.

Now complete, the project provides a range of benefits to the local area including:

  • improved safety for pedestrians, cyclists, and motorists;
  • improved travel times and increased capacity to accommodate future population growth and development needs in the area; and
  • improved access and travel times for road freight in Sydney’s south west.
