Long-term traffic changes on West Gate Freeway

22 July 2021

Drivers should look out for several changes to traffic conditions coming into effect on the West Gate Freeway from Friday, 23 July as construction on the West Gate Tunnel Project ramps up.

Lanes are being split near Grieve Parade to enable the freeway to be widened from 8 to 12 through lanes, delivering safer and smoother journeys for over 200,000 motorists who use the freeway each day.

The changes mean drivers travelling outbound from the city will need to choose their lanes earlier after the Millers Road interchange:

  • Drivers heading to Grieve Parade need to stay in the far-left lane.
  • Drivers heading to the M80 Ring Road need to stay in the two left lanes.
  • Drivers heading to Princes Freeway need to stay in the three right hand lanes.

Drivers are strongly encouraged to pick their lane early. Signs and line-marking will be in place to guide drivers.

If drivers miss their exit at Grieve Parade or the M80 Ring Road, they’ll face a 7 kilometre detour, and will have to continue on to the Princes Freeway, and U-turn at Kororoit Creek Road.

If drivers in the incorrect lane are forced to exit at the M80 Ring Road instead of continue to the Princes Freeway outbound, they’ll need to travel via the M80, U-turn at Boundary Road and take the Princes Freeway ramp.

The freeway lanes are being shifted to enable crews to set up construction sites on the freeway’s existing lanes, which will be rebuilt from the ground up.

Shifting traffic allows work to take place on various lanes of the road without having to close the freeway for extended periods of time.

The works are part of the West Gate Tunnel Project which will transform travel in Melbourne’s west. As well as improving the freeway, the project will provide an alternative to the West Gate Bridge and take thousands of trucks off residential streets.

Real-time traffic conditions are available at traffic.vicroads.vic.gov.au or via the VicTraffic mobile app. The latest public transport information and network status is available at ptv.vic.gov.au or in the PTV mobile app.
