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.

DEC 2019Night work near Meroo Road and Pestells Lane

The first Australian weathering steel bridge girders are being installed from this week on the Berry to Bomaderry Princes Highway upgrade. The 100 metre long and approximately 109 tonne girders are made from local Australian weathering steel which can last for 100 years and requires very little maintenance.

Work to install the girders will be done at night to minimise the impact on highway traffic and requires the complete closure of the Princes Highway on the night of 9 December 2019 (weather permitting).

During the closure, traffic will be detoured via Meroo Road, Railway Street and Bolong Road, Bomaderry to re-join the Princes Highway. The detours are expected to add about 6-8 minutes travel time in each direction. Detour signs and traffic controllers will be in place during the work. Residents of Pestells Lane will also be detoured via Boxsells Lane during this work.

Once the girders are in place, there will be up to 13 nights of partial highway closures (weather permitting) where traffic will alternate on one lane while work continues welding girder segments together and installing the bridge walkways.

Watch our video to find out more about the girders.

OCT 2019Introduction of no right turns at some intersections

No right turn signs will be rolled out at a number of intersections along the project, where no dedicated right hand turn lane exists.

From 1 November 2019, right turns will no longer be permitted from the Princes Highway into O’Keeffes Lane, Abernethys Lane and Jaspers Brush Road. The restrictions will also be introduced in the coming months at Turners Lane and Morschels/Devitts Lanes.

To see how these changes may affect your journey, view our handy video.

First section of final alignment now open to traffic

Traffic is now flowing on the brand new southbound lanes between Strongs Road and Wileys Creek. This is a big milestone for the project, as it is the first section of the final road alignment to become operational.

With traffic now moved onto this new section, it will allow work to begin on the new northbound lanes where the old road alignment is located.

Project information

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.

The project will:

  • increase road capacity
  • improve traffic flow
  • deliver better and more reliable journeys
  • increase overtaking opportunities
  • improve safety
  • plan for future growth
