Berry to Bomaderry - Princes Highway upgrade

Roads and Maritime Services is upgrading the Princes Highway between Berry and Bomaderry. The $450 million project will improve safety, increase road capacity, improve traffic flow and deliver better and more reliable journeys on this section of the highway.

When completed, it will be the final piece of more than 30 kilometres of highway upgraded between Gerringong and Bomaderry since work started in 2012.

Project update

For the latest project information please view or download the July 2019 project update (PDF, 1.33Mb).

Key activities being carried out between August and October 2019 include:

  • continue installing bridges planks and girders
  • shifting Princes highway traffic laterally including north of Wileys Creek and between Tandingulla Creek and Cambewarra Road to open up new areas for work
  • continue building retaining wall near Strongs Road
  • local road traffic shift at Meroo Road to allow for work to start on the new intersections and interchanges
  • completion of Boxells and Lamonds lanes turning bays
  • building new driveways to properties affected by the upgrade
  • installing drainage
  • start building the new highway pavement

Removal of overtaking lanes

Work continues to progressively remove the existing 2.3km of overtaking lanes within the Berry to Bomaderry upgrade project site.

The removal of the overtaking lanes will improve safety and reduce the frequency and severity of incidents within the worksite. Reducing overtaking opportunities will also assist drivers in adhering to road work speed limits.

The removal of the overtaking lanes will also improve the efficiency of the Princes Highway as it will allow for work to build deceleration and acceleration lanes for construction vehicles accessing the worksite, increased shoulder width and four additional break-down bays.

Project background

Major work started in September 2018. The NSW Government has engaged Downer Seymour Whyte Joint Venture (DSWJV) to build the upgrade.

Work on the upgrade will typically occur between 7am and 6pm on weekdays and between 8am and 1pm on Saturdays, excluding public holidays and weather permitting. The local community will be informed in advance if night work is required.

For the safety of workers, the speed limit between Mullers Lane, Berry and Cambewarra Road, Bomaderry has been reduced to 80km/h and a reduced speed limit of 40 km/h may apply during roadwork. There will be temporary stopping of highway traffic for up to two minutes as required while work is progressing.

Motorists should plan their trip, allow for extra travel time, keep to speed limits and follow the direction of traffic control and road signs.

Work is scheduled for completion in 2022.
