Transformation of Watson Street interchange in VIC begins

The transformation of the Watson Street interchange at the Hume Freeway in Wallan, Victoria has reached a significant milestone with major works now underway. 

Watson Street will be turned into a full diamond interchange with a new outbound exit ramp and inbound entry ramp to the Hume Freeway to help improve access for locals, freight and visitors. 

“This is a busy area for both locals and freight and once completed this major upgrade will make the intersection safer and less stressful for everyone passing through,” Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King said. 

“Starting major construction means we’re getting on with delivering a safer, more efficient interchange that keeps traffic moving while building for Wallan’s future,” VIC Minister for Transport Infrastructure and Minister for Public and Active Transport Gabrielle Williams said. 

Crews have commenced ground preparation and construction of temporary pavement to keep traffic moving while the new Watson Street interchange is being constructed. This follows site investigations, community engagement and establishment of site compound late last year. 

The temporary pavement will be laid on the north side of Watson Street between McCarthy Court and Wallara Waters Boulevard. Other works will include installing temporary safety barriers and signage, and preparation of the ground around the interchange for major construction activities to begin. 

Providing temporary pavement will allow traffic lanes to shift slightly north, maintaining one lane in each direction on Watson Street so road users can continue to travel through the area while works progress. 

These activities will mostly take place at night to minimise disruption to the public. 

“This is a major step forward for Wallan and is delivering what we promised our community. 

“With construction now underway, this upgrade will make daily trips safer and easier for families, commuters and local business,” Federal Member for McEwan Rob Mitchell said.

Once safety barriers up, crews will begin ground works which will include soil removal, establishment of environmental protection zones and vegetation management within the road reserve, supported by qualified arborists and ecologists. 

Meanwhile, the right-turn lane on the southbound Hume Freeway exit ramp to Watson Street will be closed for about two weeks. Motorists heading toward Wallan township will be able to make a U-turn at the Wallara Waters roundabout. 

Once completed in late 2027, the upgraded Watson Street interchange will improve safety, reduce congestion, and support Wallan’s continued growth. The new interchange will also strengthen connections between Hume Freeway, the town centre and the Wallan East industrial precinct. 

The Watson Street Interchange Upgrade is jointly funded by the Australian and Victorian Governments. 

Australian owned and operated company Winslow was awarded the construction contract for this project last year.

“With major works now underway, this upgrade will deliver smoother access to the Hume Freeway and better connections for residents, freight and visitors travelling through Wallan,” State Member for Kalkallo Ros Spence said. 

“It’s great to see construction begin on the new Watson Street ramps, which will make it easier for our community to travel towards Melbourne and home again while supporting Wallan’s growth,” State Member for Yan Yean Lauren Kathage said.
