M80 Capacity Improvements – Princes Freeway to Western Freeway

As part of the M80 Capacity Improvements – Princes Freeway to Western Freeway project we also:

• upgraded road safety barriers
• applied new road markings
• installed new overhead signage
• installed new ramp signals.

Construction is now complete. Over the coming months, there’ll be some closures in place while we commission the new smart freeway management system to provide real-time information for drivers using the M80 Ring Road. The smart freeway management system will be commissioned by late 2025.

When the West Gate Tunnel Project opens in 2025, and with the already completed sections of the M80 Upgrade, these additional capacity improvements will improve traffic flow and incident management on the M80 Ring Road to ensure safer and more reliable journeys.
