Works to widen the West Gate Freeway from eight to 12 through lanes are in full swing, with crews working around the clock to completely rebuild existing traffic lanes from the ground up to provide motorists a smoother and safer ride.

    To get the works done, crews have set up construction sites on the freeway’s existing traffic lanes, which means splitting lanes to create the space needed in the middle.

    From July, drivers have to decide as early as the Millers Road interchange whether they are exiting at Grieve Parade or heading towards the M80 Ring Road, or whether they stay on the West Gate Freeway heading to Princes Freeway.

    The table below will help explain what motorists need to do:

    For those wanting to exit at Grieve Parade or M80, remember to make your decision early at Millers Road – this will help avoid a 7-kilometre detour for the next available exit.

    The lane changes at Grieve Parade are the first of several lane changes that will continue to take place until the end of the project. Shifting traffic to different sides of the freeway allows work to take place on each part of the road without having to close the freeway for extended periods of time.

    The best way to be ready for these changes is for motorists to think ahead and plan routes early. Directional information and line-marking will be installed on the road to tell you what lane you need to be in to get to your intended exit ramp.  If you miss your exit, please avoid making unsafe, last-minute lane changes and wait for the next available exit.

    The West Gate Tunnel Project will provide updates to motorists in the lead up to and during lane changes.

    We understand that such changes may create inconvenience. Thank you for your patience as the West Gate Tunnel Project continues to widen the West Gate Freeway to provide a smoother and safer journey for all motorists.
