The new $342 million Nowra bridge continues to take shape with work progressing well.
There have been some major steps forward in construction of the 360 metre bridge and associated roadworks, including traffic being moved onto a new section of Illaroo Road.
Transport for NSW has released a few breakdowns on the work so far.
On the bridge work itself, concrete has been poured within 31 of the 39 steel casings.
Each pile requires around 45 cubic metres of concrete, equivalent to eight concrete trucks.
Three of 19 bridge deck segments (each around 20 metres long) have been cast and are being launched over the Shoalhaven River.
The completed deck portions are pushed via hydraulic jacks onto the top of the V-shaped piers, across bearings that are in place on each pier into its final position using low-friction pads, which allow it to slide. The whole segment is moved 20 metres north at a time.
Each double T bridge deck segment is made up of 360 cubic metres of reinforced concrete which requires up to 60 concrete trucks.
Six of eight pile caps, which are placed over the piles in the river, to act as formwork for the concrete infill. The pile tub and infill concrete connects each group of four piles below the water to each pier that projects above the water.
On the surrounding roadwork associated with the project, around 28,000 tonne of rock has been excavated next to Illaroo Road to allow for the widening and lowering of the upgraded road.
The footpath on the southern side of Illaroo Road will remain open at its current location in the short term for pedestrian and mobility access, but this will be moved later in the year to near the new lowered section of Illaroo Road as further material is excavated at this location.
Also as part of the project 98 per cent of major utility relocations are complete and 100 per cent (62km) of telecommunications cables have been relocated.
