Wallan’s key road upgrade is a step closer, with the construction contract for the Watson Street Interchange Upgrade now awarded to Winslow Infrastructure.
Big Build Roads will deliver this upgrade in partnership with the Australian-owned firm to improve access and make journeys to and from Wallan safer and easier than before.
Once complete, the project will also unlock future growth in Wallan’s rapidly expanding area and strengthen freight connections between the Hume Freeway and the Wallan East industrial estates.
Site investigations will continue through to December 2025, and crews have now started establishing the site compound to pave the way for major construction to begin in early 2026.
The project will include:
- additional freeway on and off ramps to complete the diamond interchange for traffic heading north towards Wallan and south towards Melbourne
- new traffic light intersections east and west of the Watson Street bridge
- upgraded sections of walking and cycling paths to improve local connections in the area.
This project has been jointly funded by the Australian and Victorian Governments.
The project will work to enhance freeway access for Melbourne’s growing northern corridor and is part of a significant investment into major transport projects to improve access, safety, and connectivity.
