Duncans Road Interchange, Werribee

We’re making Duncans Road interchange better for all road users by improving access to the freeway and popular tourist attractions in Werribee.

Project update

The road design is currently being finalised ahead of works starting in late-2018.  

Some of the first activities that we’ll get started on include: 

  • surveying, geotechnical studies and soil testing
  • relocating utility services
  • building drainage for the new roads
  • building retaining walls.

To carry out the works safely, we’ll install fences around our worksite. We understand that businesses and residents will need access during the works so we’re working closely with our contractors to ensure that access is maintained during construction activities. 

Project background

More than 11,000 cars and trucks use the Duncans Road interchange every day, with this number surging during events in the tourism precinct.

The interchange is a key route for a number of growing suburbs, connecting you to the Werribee town centre and Wyndham Harbour.

The existing bridge was built in 1959 and struggles with today’s traffic volumes Additionally, there’s no outbound freeway exit and no inbound freeway entrance to and from Geelong.

This upgrade will make traffic flow better, so you can get to where you need to be sooner and safer. 

About the project

Project details

At this interchange, we’re:

  • building new exit ramps from the Princes Freeway to Duncans Road
  • building two new bridges over the Princes Freeway, providing two lanes in each direction
  • adding two new ramps for the Princes Freeway at Duncans Road with an entrance for Geelong-bound traffic and an exit for traffic coming from Geelong
  • improving the intersection of K Road and Duncans Road
  • building new walking and cycling paths along Duncans Road and safe road crossing areas.


Here are just some of the benefits you’ll experience when travelling through this busy interchange:

  • improved journeys to world class tourist attractions, including Werribee Open Range Zoo, Werribee Mansion, the National Equestrian Centre and the Victorian State Rose Garden
  • new ramps will make it easier to get to and from Geelong and in and around Werribee’s popular tourist attractions
  • increased safety by improving the busy K Road intersection
  • smoother journeys between Werribee and Geelong
  • a more active lifestyle with paths on the Geelong side of the bridge for walking and cycling.
