The $125 million Jervis Bay Road and Princes Highway intersection upgrade in New South Wales is on track to beginning early works this year as the project reaches new milestones. 

Overwhelming support for the proposed design was shown through the release of the submissions report that reflects 146 submissions on the concept design and environmental assessment – which has already been approved. 

“The community, businesses and stakeholders had the opportunity to provide their thoughts and helped inform improvements to the design, which is now being progressed. 

“Key changes to the intersection between Jervis Bay Road and the Princes Highway will involve realigning and widening the highway and an overpass bridge over Jervis Bay Road which will provide a better connection for road users. 

“According to the survey results, 96 per cent of respondents strongly agree or agree the proposal will improve safety, 89 per cent strongly agree or agree it would improve resilience, and 94 per cent strongly agree or agree it would improve efficiency,” NSW Minister for Regional Transport and Roads Sam Farraway said. 

According to State Member for South Coast Shelley Hancock, community feedback was vital in getting the design right for this project. 

“The community offered some great insights that have helped the project team make additions and changes to the project to better serve the local community. 

“The South Coast is growing rapidly and the road infrastructure must keep pace with that growth which is why I have been a strong advocate for upgrades to our major highways on the South Coast,” Mrs Hancock said. 


The concept design for the Jervis Bay Road and Princes Highway intersection upgrade will include: 

  • A new intersection between Jarvis Bay Road and the Princes Highway that incorporates: 
  • Realignment of the existing Princes Highway, including widening from two lanes to a four-lane divided highway (two lanes in each direction), with media separation using flexible safety barriers, providing an uninterrupted through alignment for the Princes Highway 
  • An overpass bridge for the Princes Highway over Jervis Bay Road 
  • Two single-lane roundabouts below the overpass bridge to provide direct access from Jervis Bay Road and Old Princes Highway to Princes Highway as well as from the Princes Highway to Jervis Bay Road and Old Princes Highway 
  • Direct connection to existing properties and businesses at the Old Princes Highway 
  • A connection from Willowgreen Road to Old Princes Highway 
  • Tie-ins with the Old Princes Highway and with Jervis Bay Road 

“The upgrade, including a flyover and roundabouts on either side, will make the intersection of Jervis Bay Road and the Princes Highway safer for all road users. 

“This will improve freight productivity, efficiency and network reliability, reduce congestion and support the economic growth of the region. 

“We are committed to delivering the road infrastructure that locals, tourists, businesses and freight operators need on the South Coast,” Senator for New South Wales Perin Davey said.

In addition to the release of the submissions report, Transport for NSW also announced that Arcadis Australia Pacific Pty Ltd has been awarded the contract to undertake detailed design, which works have already commenced. 

The Jervis Bay Road and Princes Highway intersection upgrade is jointly funded by the Australian and New South Wales Governments, each contributing $100 million and $25 million respectively. 

Early works will begin late this year and construction is estimated to take up to three years to complete.
