Ison Road Overpass project hits new heights

Back to Newsfeed

The Ison Road Overpass project has hit new heights – literally – as it works toward helping link Wyndham West with the Princes Freeway.

Since December 2023, crews have placed and compacted 15,300 truckloads of soil to form towering embankments for the overpass bridge approaches.

Rising to a height of 8 metres, the embankments have become a prominent landscape feature on either side of the Melbourne-Geelong railway line at Werribee. The project has trucked in 236,000 cubic metres of soil to build the embankments – enough to fill 94 Olympic swimming pools.

Crews have also made significant progress with the completion of piling works to help build the foundation for the overpass, installing more than 1000 steel-reinforced concrete piles.

With the project continuing apace, an average of 60 people are working on-site daily in a variety of roles. Combined, they have worked over 60,000 hours since work on the overpass began in November.

Once complete, the 4 lane overpass will extend over the Melbourne-Geelong railway line toward the Princes Freeway. Future-proofed for 6 lanes, it will give residents access to surrounding areas and minimise traffic in central Werribee, reducing congestion and improving journey reliability.

The project’s opportunities for active transport will include shared walking and cycling paths over the bridge and a cycling path underneath the bridge.

The Victorian and Australian governments will invest a total $114 million to deliver the project.

Due for completion by the end of 2025, the Ison Road Overpass is set to cater for nearly 29,000 vehicles a day by 2036.
