The site remains a hive of activity, with work not only continuing feverishly on the bridge's construction itself, but on the associated roadworks around the area.

Seven of the 19 bridge segments for the Nowra Bridge project have now been cast and launched, meaning the project is over a third of he way across the 360-metre span.

A Transport for NSW spokesperson said it takes around two weeks between each bridge segment being cast.

Each bridge segment has around 36 cubic metres of concrete and they are launched into position three to seven days after being cast.

Each bridge deck segment is around 20 metres long.

They are cast on the southern side of the river and then pushed into place by hydraulic jacks onto the top of the V-shaped piers.

The deck travels across bearings that are in place on each pier, to its final position using low-friction pads, which allow it to slide.

The whole segment is moved 20 metres north at a time.

Work to complete the bridge piers is also continuing, with six of the nine now finished.

Work continues on the final piles on the northern side of the bridge, while the northern buttress, on which the bridge will connect, is also in place.

Roadworks across the site continue with a massive amount of work being done on Illaroo Road.

Traffic has shifted onto the new lowered, northern section in a temporary arrangement, with two lanes operating in each direction together with the new roundabout at the intersection of Illaroo Road and Fairway Drive.

This temporary arrangement will remain in place until mid-2022.

Work is well underway to widen and lower the southern side of Illaroo Road.

This will eventually allow for the final seven lanes of traffic at the Illaroo Road intersection.

On the southern side of the bridge, the Princes Highway has been widened to the west and traffic has transferred onto the new section of roadway in front of the Shoalhaven City Council administrative building.

Massive amounts of work is also being undertaken in and around what used to be home to the 'Welcome to Nowra' sign which will now be an integral part of traffic flow on and off the bridges when work is complete.

Weather permitting, the project is on track to be completed in mid-2024.
