Update - June 2026

Major works started in December 2025 and will take approximately 12 months to complete.

During major works, there will be significant disruptions at the intersection and surrounding roads. Please look out for signs, follow the direction of traffic controllers and allow for extra time when travelling through the area.

The contractor will minimise disruptions as much as possible.

Disruptions - major works

Crews will be on site Monday to Saturday between 7am to 6pm, with nightworks required at times. To keep everyone safe, speed limits will be reduced to 40km/h and single lane closures will be in place near the intersection.

Road closures and detours will be required during works on Plumpton Road and Golf Course Road. Details of closures and detours will be published on this page when confirmed.

The Western Highway and Henty Highway will remain open.

Traffic controllers will be on site to help road users travel safely through the area. Crews will aim to minimise delays and access impacts as much as possible.

Access to residential properties and businesses will be maintained during the majority of the project. The contractor will contact impacted residents or businesses about temporary access changes, if required.

Please note: dates and timeframes of these works are dependent on a range of factors, including favourable weather and site conditions.

Changed traffic conditions and closures

Please be aware of changed traffic conditions to allow for further construction on the Western and Henty highways. During this stage, the intersection will begin to function as a roundabout. Golf Course Road, Plumpton Road and the Henty Highway are open to traffic in both directions. Temporary barriers and yellow line marking are in place to delineate the site.

The Western Highway remains open to traffic in both directions.

Derry Parade – changed access to/from the Western Highway

Access in and out of Derry Parade at the Western Highway is temporarily closed. A detour will be in place via Williams Road and Citrus Avenue until mid-late July.

Service lane restrictions

There are restrictions to the service lanes on the eastern side of the Western Highway until mid-late July.

The service road exit, just north of Derry Parade, is temporarily closed. Impacted residents can exit the service road, near the bus stop. Access changes are also in place on the service road south of Derry Parade – please follow all roadwork signs in the area.

There will be no changes to bus stops/services or council services.

Background

The intersection of the Henty Highway, Western Highway, Golf Course Road and Plumpton Road is one of Horsham’s key entrance points and caters for 18,000 vehicles per day, with 18 per cent of the volume heavy vehicles. Between 1 January 2019 and 31 December 2023, there were 12 crashes at or near this intersection, with six resulting in serious injuries.

The Western and Henty Highways are relied on heavily by farming industry, grain production, regional tourism and manufacturing services. Golf Course Road and Plumpton Road service an industrial zone and are used heavily by freight.

With traffic flow anticipated to increase due to population and industry growth in the region, we are constructing a new roundabout to simplify the intersection, and improve safety and efficiency for all road users.

Benefits

Reduced risk and severity of crashes
Improved access and traffic flow
Increased network capacity resulting in improved travel times and freight efficiency
Better access for local businesses
Safer and more accessible movements for pedestrians and cyclists
