Project Background

The roundabout at Caroline Springs Boulevard and Rockbank Middle Road is currently one of busiest intersections in the City of Melton. There are traffic delays at the roundabout and there are safety concerns for pedestrians and cyclists.

Installing traffic lights will help control vehicle movements, manage congestion during peak periods and provide safe crossing locations for pedestrians and cyclists, thereby encouraging walking and cycling.

The project will include:

  • Removal of existing roundabout
  • An expansion and realignment of the road
  • Installation of traffic signals
  • Landscaping
  • New public lighting
  • Underground services relocations (electricity, water, gas, and communications)

Works began in late November 2023 and is due for completion by early 2025.

Project updates

February 2024 update

The next phase of works to upgrade the Caroline Springs Boulevard and Rockbank Middle Road intersection with traffic lights will begin on Sunday 18 February until late 2024.

Initially, we will be working on the south-western corner of the intersection to construct the new lanes and traffic lights, before starting work in stages on each corner.


The following traffic changes will apply from Sunday 18 February:

  • From Rockbank Middle Road, you will only be able to turn left onto Caroline Springs Boulevard and traffic will not be able to cross the intersection.
  • No right turns will be possible from both Caroline Springs Boulevard or Rockbank Middle Road.
  • Follow the detour signs to the next roundabout on Caroline Springs Boulevard at either Bridgewater Terrace or The Grove/Anderson Ave, to travel back to Rockbank Middle Road.
  • A lane closure will apply in the northern direction.
  • 40km/h speed limits will apply during construction hours.

These changes will mean we can keep Caroline Springs Boulevard and Rockbank Middle Road open whilst we upgrade the intersection.

Night works

Night works will occur from 7pm on Sunday 18 February until 5am Monday 19 February while concrete barriers and new traffic management arrangements are installed on Caroline Springs Boulevard and Rockbank Middle Road. You may experience low to medium noise levels during this time.

Lauriston Quay

The Lauriston Quay exit is closed until mid-2024. During this time, local traffic is being detoured via Bridgewater Terrace onto Caroline Springs Boulevard.

What to expect during the works

  • Expect major delays, so please allow additional travel time, or seek alternative routes.
  • Construction works will be between 7am and 6pm on weekdays.
  • During these works, pedestrian access and all school crossings will be maintained, but some pedestrian detours will be in place.
  • Some low to medium level noise
  • Please follow the direction of all traffic signage and traffic controllers during the works.

Frequently asked questions

Due to complicated nature of construction works which will be carried out under live traffic conditions, the works are expected to take approximately 12 months to complete which is early 2025.

We will keep Rockbank Middle Road and Caroline Springs Boulevard open, so we’ll be completing the works in five stages to keep the roads open with detours in place.

This intersection upgrade cannot be upgraded without expanding the road footprint through additional lanes and turning lanes, plus new footpaths, which required the removal of several mature trees.

We experimented with reducing the length, width and alignment of these lanes to mitigate losses and we also engaged the help of an arborist to assist with the design.

We will delivering extensive landscaping, new tree plantings and garden beds to offset the tree loss.

Approximately, 70 Spotted Gum and Red Box trees and more than 4000 shrubs will be planted at the appropriate time for planting.

This project does not include duplication of Rockbank Middle Road, west of this intersection. We see this portion of road as an upgrade required in the medium term and expect it will be upgraded in 5-10 years.

Whilst we aim to complete the works during quieter periods, Caroline Springs Boulevard and Rockbank Middle Road is one of the busiest intersections in the City of Melton.

To complete the project, it is not possible to avoid disruption to traffic and the community is encouraged to seek alternative routes where possible.

We will give as much notice as possible on detours and traffic changes to the local community, businesses, sporting groups and schools, so people can plan ahead.
