We’re upgrading two intersections along Sunshine Avenue in Taylors Lake to improve safety and traffic flow.

Project status:

Planned

What we're doing

Big Build Roads is upgrading the roundabouts at Sunshine Avenue and Melton Highway, and Sunshine Avenue and Old Calder Highway on behalf of Transport Victoria to improve safety and traffic flow.

The upgrade of the Sunshine Avenue and Melton Highway roundabout will:

add new dedicated turning lanes
extend current turning lanes
install a set of traffic lights on Melton Highway to help balance traffic flow.

The upgrade of the Sunshine Avenue and Old Calder Highway roundabout will:

add an additional right turn lane on Old Calder Highway
upgrade the pedestrian crossing on Shoppers Lane.

Benefits

The intersection upgrades will:

improve road safety
improve traffic flow
reduce congestion
improve connectivity for pedestrians.

Funding

This project is part of the Victorian Government’s $117 million investment in the Metropolitan Road and Intersections Upgrade Program.

Planning update

To inform decision-making we undertook a range of technical assessments including:

traffic data collection and modelling to assess the current capacity of existing road conditions
identifying potential risks and impacts to the construction program and how these could be mitigated to minimise impacts to the community, businesses and motorists.

What’s Next

Planning work is progressing, as the upgrades move towards construction. Key activities include:

on-site investigations to test ground conditions
developing the project design and construction approach
environmental investigations to better understand flora, fauna and tree species.

From Monday 27 July to late August 2026, crews will be working at the Sunshine Avenue and Old Calder Highway roundabout to undertake site investigations.

Day works will occur between 7am and 6pm, Monday to Friday.

Traffic Impacts

These works will take place under temporary lane closures and reduced speeds along Sunshine Avenue and Melton Highway.

On Tuesday 4 August 2026, between 9am and 3:30pm, Shoppers Lane will be closed in both directions at the Sunshine Avenue roundabout. Detours will be in place, please refer to the map on the next page. Delays of up to 10 minutes are expected.

Traffic disruption will be kept to a minimum, and busy periods will be avoided, where possible.

These works are being completed during off-peak times while traffic volumes are lower, to minimise impacts on local businesses and road users.

Weather conditions may affect our progress. Please visit bigbuild.vic.gov.au or refer to roadside messaging for the most up-to-date information.

Access to businesses and driveways will be maintained at all times.

Planning and early works for the intersection upgrades are expected to be complete in 2026. Timelines for major construction will be known once our planning is further progressed.
