What’s been happening
We’re making great progress building the new Ison Road overpass and extension, and we’re on track to open the road in September – 3 months ahead of schedule!
Work is continuing at a rapid pace on the Extension which will connect the Overpass to Geelong Road (Princes Highway), and is being delivered by Victoria’s Big Build, on behalf of Wyndham City Council.
Since we commenced work on the Extension in March 2025, we have completed the majority of the earthworks and drainage installation, including 3 large culverts. Asphalt has been laid near the Browns Road intersection and concrete has been poured to create the walking and cycling path.
Upgrade works at the intersection where Ison Road will connect with Geelong Road/Princes Highway, West Road and Werribee Main Road are underway, which will soon have traffic lights.
On the Overpass, we have completed earthworks and asphalting to connect the road to the existing Ison Road in the north and the Extension in the south, finished pouring the concrete for the walking and cycling paths, installed street lighting and are continuing landscaping.
While the new Ison Road overpass and extension will open in September, we will still need to undertake some finishing work until the end of the year, including landscaping, switching on the new street lights, placing the final layer of asphalt and line marking.
Upcoming works
