Nowra Bridge project - Princes Highway upgrade

Roads and Maritime Services is planning for a new four lane bridge over the Shoalhaven River, upgraded intersections and additional lanes on the Princes Highway. The project would improve traffic flow and ease congestion on a major section of the Princes Highway and deliver faster and more reliable journeys within the Nowra-Bomaderry area.

The NSW and Australian Governments have each committed $155 million to the project.

Updates and announcements

Call for design and construction tenders

We are inviting contractors to express their interest in designing and building the project. More information on the tender process is available at the tenders website.

Geotechnical investigations, including nightworks

We are completing night work to carry out underground investigations. This will involve drilling holes next to and under the highway to collect soil and rock samples to help finalise the design of the project.

To minimise disruption to motorists, work will be carried out between 6pm to 4.30am from Sunday 04 November until Friday 16 November 2018, weather permitting. For the safety of workers and motorists, lane closures and a reduced speed limit of 40 km/h will be in place during work hours and may affect travel times by up to five minutes.

For the latest updates visit or call 132 701.

Environmental assessment and concept design

Roads and Maritime displayed the environmental assessment and concept on the Nowra Bridge Project in August and September 2018. The community was invited to have their say on the project until Friday 28 September.

Please view or download the Review of Environmental Factors. It looks at the potential impacts of the project and identifies ways to protect the environment and community

The concept design provides a higher level of detail for the bridge, intersection and road designs.Please view the interactive online portal to experience the concept design including fly-over and 360-degree animations, before and after images and improvements to your future journey.

Preparing the submissions report

Following the recent display period, Roads and Maritime will review all submissions. A submissions report will then be prepared which will consider and address all feedback raised by the community. This report will be available to the community later this year and will be used to assist the team in developing the detailed design.

Summary of the preferred option community consultation

Roads and Maritime asked for community feedback on the preferred option between Monday 19 February and Friday 23 March 2018.

The consultation included:

  • five community information kiosks attended by more than 630 community members
  • a survey completed by 250 community members
  • project information delivered to all residential properties in the Nowra-Bomaderry area and displayed at advertised locations, in local newspapers, on Facebook and on the Roads and Maritime website.

Project background

This project is being developed to improve conditions on the Princes Highway over the Shoalhaven River in Nowra.

During early investigations, the project team identified some key issues with the current crossing of the Shoalhaven River at Nowra:

  • Increasing maintenance difficulties with the old Nowra Bridge
  • Increasing congestion issues in peak times from local traffic
  • Some large and heavy trucks cannot use the old Nowra Bridge
  • High risk of damage and closure of the old Nowra Bridge from an impact by an over height vehicle
  • Increased demand and future traffic growth
  • Higher than state average annual crash rates on the Princes Highway leading up to the bridge.

Around 50,000 vehicles cross the Shoalhaven River on an average day. Any extensive closures of the iron truss bridge due to maintenance or emergency repairs would cause major delays to the network around Nowra. During early planning it became clear that the project should focus on a new bridge that could address these key issues.

Preferred option

Based on multiple options assessment exercises a preferred option for the project was determined and put on display for community feedback between 19 February 2018 and 23 March 2018.

The preferred option includes:

  • A new northbound four lane bridge
  • Reconfiguration of the existing concrete bridge to carry southbound traffic
  • Intersection upgrades at Illaroo Road, Bolong Road and Bridge Road
  • New Pleasant Way T-intersection
  • Keeping the old southbound bridge for pedestrians and cyclists.

Key benefits include:

  • Improved safety, capacity and efficiency across the Shoalhaven River
  • Improved freight movements and access to the South Coast
  • Better traffic flow now and in the future
  • Improved pedestrian connectivity
  • Preserving the heritage of the old southbound bridge

More information on the preferred option can be found in the Nowra Bridge Project Preferred Option Report or in the Frequently Asked Questions.
