THE long-awaited transformation of Wallan’s key entry point to the Hume Freeway is officially under way, with preparations for the Watson Street Interchange Upgrade progressing steadily ahead of major construction in early 2026.
The $175 million project, set to significantly improve traffic flow and safety, will deliver a new diamond interchange featuring additional freeway access for motorists travelling north towards Wallan and south towards Melbourne. Signalised intersections on either side of the interchange will complete the upgrade, aiming to reduce congestion and streamline movement through one of the region’s busiest pinch points.

Recent community information sessions drew hundreds of locals eager for updates and reassurance that long-standing traffic frustrations may soon ease. Many pointed to the growing pressures on the Northern Highway, describing peak-hour delays as increasingly unsustainable for a town expanding as rapidly as Wallan.
Residents from Wallara Waters, one of Wallan’s largest newer estates, were among those welcoming the project.
“The upgrade means I won’t need to cross the bridge to travel into the city, which will save me time during peak hour,” one resident said, echoing a widespread sentiment of relief.
The upgrade is being delivered by Winslow Constructors, one of Australia’s largest civil contractors with extensive experience in major road and infrastructure projects across Victoria.
Winslow has now begun establishing its site compound in Wallan, marking a significant step in transitioning from planning to on-ground preparation. The company is known for managing complex builds under tight timelines and for engaging local subcontractors, an approach that has already been positively received by the business community.
Early works have been progressing since August 2025, when site investigations commenced. Major construction is scheduled to begin in early 2026, signalling the start of a major infrastructure overhaul set to reshape how thousands of commuters access the Hume Freeway each day.
