Drivers in Melbourne’s west can now enjoy safer and more reliable access to the Princes Freeway and Werribee tourism precinct, thanks to the completion of the Duncans Road Interchange Upgrade in Werribee.
Member for Werribee Tim Pallas today announced the opening of a new Princes Freeway entry ramp for Geelong-bound traffic, the latest improvement to the busy interchange as part of the Western Roads Upgrade.
It follows the completion of a new Melbourne-bound freeway exit ramp, which opened to traffic in November.
A new four-lane bridge over the Princes Freeway has also been built as part of the project, replacing the old narrow two-lane bridge, to cater for current and future traffic demands.
Extra lanes and upgraded traffic lights have been added to the busy K Road and Duncans Road intersection to improve safety and traffic flow through the interchange.
The Duncans Road Interchange Upgrade features more than 650 metres of new walking and cycling paths, as well as new safe road crossing areas.
The Werribee tourism precinct is important to the growth of Melbourne’s west and is home to several popular attractions including the Werribee Open Range Zoo, Werribee Mansion and the National Equestrian Centre.
Improvements to the Duncans Road Interchange will significantly improve access to these attractions, particularly when they resume hosting major events.
Landscaping and some other minor works on the Duncans Road Interchange will continue over the coming months.
The Western Roads Upgrade is improving eight major roads across Melbourne’s west to make it quicker, easier and safer for all road users. It will give local businesses opportunities for growth, improve access to jobs and boost safety for cyclists and pedestrians.
Upgrades to Dunnings Road and Palmers Road in Point Cook, Dohertys Road in Truganina and Laverton North, Leakes Road in Truganina, Derrimut Road in Tarneit and Forsyth Interchange in Hoppers Crossing are now complete.
The final remaining Western Roads Upgrade project, Palmers Road between the Princes Freeway and the Western Freeway, is due to be completed in the coming months.
The Western Roads Upgrade also includes the resurfacing of 37 roads to improve quality and safety, and the maintenance of more than 260km of road from Footscray to Werribee for the next 20 years.
More than one thousand workers have helped deliver the Western Road Upgrade, with those workers having contributed more than 4 million hours since construction started in late 2018.

The Government’s $1.8 billion Western Roads Upgrade is being delivered by Major Road Projects Victoria.
