Berry to Bomaderry - Princes Highway upgrade

Roads and Maritime Services is upgrading the Princes Highway between Berry and Bomaderry.

The construction contract for the 10.5 kilometre highway upgrade project was awarded in May 2018.

Downer/ Seymour Whyte will build the four lanes of new divided road between Mullers Lane at Berry and the Cambewarra Road roundabout at Bomaderry in addition to building temporary roads and carrying out road work for the safety of motorists and workers.

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.

The NSW Government has committed to completing the highway upgrade and has provided $19 million in 2017/18 financial year to start construction.

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.

Speed limit reduced to 80km/h

For the safety of workers, the speed limit between Mullers Lane, Berry and Cambewarra Road, Bomaderry has been reduced to 80km/h

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 will generally be carried out Monday to Friday between 7am and 6pm and reduced roadwork speed limits may apply. There will be temporary stopping of highway traffic for up to two minutes as required while work is progressing.
