South Nowra - Princes Highway Upgrade

The 6.3 kilometre Princes Highway upgrade between Kinghorne Street and Forest Road improves traffic flow for both local and 'through' travelling motorists on this busy section of the Princes Highway.

Updates and announcements

The $72 million Princes Highway upgrade at South Nowra was officially opened by the Minister for Roads and Ports and Member for South Coast on Saturday 29 March 2014.

The 6.3 kilometre Princes Highway upgrade between Kinghorne Street and Forest Road will improve traffic flow for both local and ‘through’ travelling motorists on this busy section of the Princes Highway.

The completion of this highway upgrade is another step towards Roads and Maritime achieving its commitment to provide two lanes in each direction from Waterfall to Jervis Bay Road.

Project benefits

  • Consistent four lane travel conditions on the Princes Highway between Bomaderry and Jervis Bay Road
  • Improved road safety by reducing conflicts between through traffic and local traffic accessing business premises
  • Improved road safety by providing a central median, along with more opportunities to safely overtake slower vehicles
  • Improved travel times for motorists
  • Improved access to many business properties
  • Improved safety and facilities for pedestrians and cyclists

Key features

  • Enhanced travel efficiency for through traffic with the provision of three lanes on the eastern side of the highway between Quinns Lane and Warra Warra Road
  • A 2.5 metre wide shared footpath / cycleway on the eastern side of the highway between McKay Street and Warra Warra Road for cyclists and pedestrians
  • An on road cycle facility south of Warra Warra Road
  • Pedestrian activated traffic lights on the Princes Highway at the Park Road cul-de-sac
  • Changes to Nowra Hill Road to a left in, left out intersection
  • Relocation of the existing BTU Road intersection to approximately 400 metres north of its original location. The new intersection has been reconstructed to allow all turning movements
  • Reconstruction of the Forest Road intersection to allow all turning movements
  • A dual lane roundabout at the junction with Hillcrest Avenue
  • A heavy vehicle inspection area to the south of Hillcrest Avenue
  • Improvements to the existing service road between Quinns Lane and Central Avenue to a two lane road on the western side of the highway for improved road safety and accessibility
  • Construction is currently underway to build a new road shoulder, in the northbound direction, between Forest Road and Parma Road.

Green and Golden Bell Frog

Major construction on the upgrade started in November 2011 but stopped when several endangered Green and Golden Bell Frogs were found on and adjacent to the project site.

Work was delayed while plans were put in place to protect the frogs under the requirements of state and commonwealth legislation.

Roads and Maritime engaged the Australian Research Centre for Urban Ecology to undertake a three year population study. This study commenced in November 2013 with field investigations of sites around Nowra being undertaken.

This study will continue for three years with individual surveys undertaken three times per active season (November to April).
