Project update - June 2024

Before we can commence construction on the intersection we need to relocate the Greater Western Water fresh water pumping station and pressure release station.

The pumping station will be moved 450m west of its current location. These complex works are expected to be complete by the end of 2024, weather permitting.

What to expect

To relocate the water pumping station we need to identify all the underground services around the intersection including services that are connected to the pumping station – this is called service proving. 

Contractors will undertake service proving work in stages at different locations around the intersection and in the road reserve. 

Work to install new underground pipelines and relocate the pumping station will begin after the service proving.

Melton Highway full weekend closure and detours

As part of these works, Melton Highway will be fully closed on the western side of the Leakes Road intersection from 7pm Friday 14 June to 5am Monday 17 June.

While we prepare for these works, at times the speed limit on Melton Highway will be reduced to 40km/h from Monday 10 June to Friday 14 June.

Work will take place during the day and at night. Crews use modern equipment to keep noise to a minimum. However, the works will unavoidably produce noise and temporary lights will be used.

There will high noise levels at night, including machinery sounds and excavation noise. For the safety of road users and workers, reversing beepers are a requirement on all machinery.

Detours

During the works, detours will be in place. Please allow additional travel time of up to 20 minutes.

Road users in light vehicles who wish to travel east along Melton Highway have two detour options:

  • Travel from Melton via Gisborne-Melton Road, Diggers Rest-Coimidai Road, Holden Road and Leakes Road to re-join the Melton Highway at the Leakes Road intersection. 
  • Travel from Melton to the Western Freeway and join the inbound lanes, exit at Leakes Road and re-join the Melton Highway at the Leakes Road intersection. 

Road users in light vehicles who wish to travel west along Melton Highway have two detour options:

  • From the Leakes Road intersection follow Leakes Road to Holden Road, Diggers Rest-Coimidai Road towards Toolern Vale and then Gisborne-Melton Road to Melton. 
  • From the Leakes Road intersection follow Leakes Road to the Western Freeway and join the outbound lanes, exit at Ferris Road/Melton Highway and travel into Melton. 

Please obey signage and follow the directions of traffic controllers as they guide you through the area. 

Heavy vehicles detour routes

Heavy vehicles travelling east have two detour options:

  • Travel from Melton via Gisborne-Melton Road, Diggers Rest-Coimidai Road and Vineyard Road to join the inbound lanes of the Calder Freeway, exit at Kings Road and rejoin the Melton Highway. 
  • Travel from Melton to the Western Freeway and join the inbound lanes, exit at Leakes Road and rejoin the Melton Highway at the Leakes Road intersection. 

Heavy vehicles travelling west have two detour options:

  • Leave the Melton Highway at Kings Road and then join the outbound lanes of the Calder Freeway. Exit at Vineyard Road, follow Diggers Rest-Coimidai Road to Toolern Vale and Gisborne-Melton Road to Melton.  
  • Turn south on to Leakes Road at the Melton Highway intersection, join the Western Freeway outbound lanes, exit at Ferris Road/Melton Highway and travel into Melton. 

Please obey signage and follow the directions of traffic controllers as they guide you through the area. 

 
Water relocation works

During the pumping station relocation works, you can expect:

  • Crews will work during the day, Mondays to Fridays. There may be times when we will need to work at night, between 8.30pm and 5.30am, when traffic volumes are at their lowest.
  • Some lane closures and temporary reduced speeds of 40km/h during work hours. We will advise community about any upcoming changes to traffic movements. 
  • Medium to high levels of noise from equipment and machinery such as generators, excavators and trucks.
  • Traffic management will be in place to assist road users and pedestrians. Please follow signage and directions from traffic controllers, as required, to keep you and our workers safe.

Please plan ahead and allow 10 minutes of extra travel time when moving through the area.

What we're doing

To make it safer and easier to travel through the intersection of Melton Highway and Leakes Road, we’re aligning the intersection to a traditional cross road, adding turning lanes and installing traffic and pedestrian lights.

Works to relocate services commenced in mid-2023 with no impact to neighbouring properties or motorists. Works to relocate the Greater Western Water fresh water pumping station will have some impacts to motorists. There will be no disruption to water supply during these works.

We’ll be aligning the current staggered intersection to a traditional cross road with traffic and pedestrian lights.

We will also:

  • relocate vital utility services to ensure we can safely work to realign the intersection
  • widen the intersection to allow for turning lanes and improved lane configuration
  • resurface the area and apply new line marking
  • install new street lighting to create a safer road environment at night
  • build new kerbing and improve drainage 
  • remove and trim some vegetation to improve sight lines.
