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.

Updates and announcements

Major work underway

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.
