Construction ramping up on $114M Ison Road Overpass

Works on the Ison Road Overpass in Victoria are powering ahead, with the first two of three piling rigs having now arrived on site.

When complete, the Ison Road Overpass will provide a four-lane overpass that will extend over the Melbourne-Geelong railway line toward the Princes Freeway.

Future-proofed for six lanes, the Ison Road Overpass will give residents access to surrounding areas and minimise traffic in central Werribee, reducing congestion and improving journey reliability. The overpass is expected to cater for close to 29,000 vehicles daily by 2036.

The piling rigs will help to establish a bridge foundation. The machines will help crews construct around 1000 steel reinforced concrete piles up to 12 metres deep and nearly a metre in diameter. The piling rigs can extend up to 21 metres high, with the biggest of the three rigs weighing 124 tonnes.

Earthworks are also underway to raise ground levels for the overpass road, with trucks starting to bring in the 200,000m³ of fill material that will form ramps on each side of the bridge.

Piling works on the project began in January and are due for completion in June. Initial works on the project began in November 2023.

The Federal and State governments will invest $114 million to deliver the project, which is set to be completed by the end of 2025.
