We're upgrading 8 main roads in Melbourne's west as well as improving and maintaining more than 260km of road from Footscray to Werribee.

Current works

Duncans Road Interchange, Werribee

We’re widening the Melbourne-bound freeway median strip to prepare for the new entry ramp. We’ll install more protection for existing gas lines and bore under the freeway to install utilities. This means some off-peak daytime lane closures as well as an overnight lane closure.  During the closures, speeds will be reduced to 40km/h.

Why the Duncans Road Interchange?

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.

Project details

At the Duncans Road 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 on this busy road:

  • 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
  • reduced congestion and increased safety by improving the busy K Road intersection
  • better access for locals to shops and jobs.
