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.

Major work underway

Major work started in August and 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.

Extended working hours will be required on Saturdays between 7am and 6pm to complete electrical relocations from late September 2018. We expect to complete this work by December 2018, weather permitting.

Work is scheduled for completion in 2022.

Motorists are advised of changed traffic conditions on the Princes Highway for safety improvement work to be carried out between Mullers Lane, Berry and Cambewarra Road, Bomaderry.

To minimise impact to motorists, night work will be carried out for five weeks from Monday 13 August between 7pm and 5am Monday to Thursday, weather permitting.

Traffic control and a reduced speed limit of 40 km/h will be in place for the safety of workers and motorists.

Improving road safety and accessibility into Croziers Road, Jaspers Brush, from the highway

In March 2018, a temporary protected right turning lane was built at the Croziers Road and Princes Highway intersection to improve road safety and accessibility for motorists. View or download the Croziers Road diagram (PDF, 169Kb) to see the range of safety work that has been completed or is in development at the intersection.

The work includes a designated right turning lane, removal of the bus stop and the installation of additional guard rails.
