Eleven super-T girders have been lifted into place at Jervis Bay Road intersection forming the base of the new bridge that will significantly improve traffic flow and safety in the region.

The pre-cast concrete girders form the deck for the new overpass bridge that will allow traffic on the Princes Highway to move uninterrupted while Jervis Bay Road traffic flows under the bridge.

Manufactured in Newcastle, each girder weighs 47 tonnes and spans 28 metres in length. The girders were carefully transported the 400-kilometre journey to the project between the hours of 11pm and 3am on five separate loads under strict safety protocols.

Due to the size and complexity of the girder installation, work was carried out at night, with a crane lifting two to three girders per night directly from the delivery truck into position.

Measures were put in place to minimise noise to the local area and construction impacts to the Princes Highway.

The milestone installation allows the construction of the bridge to take shape, with a mid-2026 completion target. The project is on track for completion in 2027, weather permitting.

Work on the construction of the new eastern roundabout also continues. This roundabout will allow traffic to efficiently move between the Princes Highway and Jervis Bay Road, which provides the key linkage to Huskisson and other bay and basin villages.

Asphalt work will be carried out this week from Wednesday 22 October, and the roundabout will be partially opened to traffic in late October.

The completion of the roundabout is expected later this year, in time for the upcoming busy summer holiday period.

Quotes attributable to Member for Gilmore, Fiona Phillips:

“Today marks an exciting major milestone for this intersection which sees the highest volume of traffic on the Princes Highway between Nowra and the Victorian border.

“The intersection upgrade will transform travel along the NSW South Coast and provides a key link to Huskisson and surrounding villages.

“When they drive by, motorists can see that construction on the Australian and NSW governments’ $164 million Jervis Bay Road intersection is really taking shape.

"With the huge task of installing 11 pre-cast super-T concrete girders now complete, crews will start construction on the new deck for the new overpass bridge.”

Quotes attributable to Member for Kiama, Katelin McInerney:

“I am excited to see the progress on the Jervis Bay Road intersection upgrade with this milestone also marking more than 230,000 hours of work already completed on the project to date.

“This milestone is a key step on the journey to delivering a safer, more reliable intersection for the NSW South Coast with full project completion on track for 2027.”
