South Belt/Southbrook Road Intersection

To improve traffic flow, traffic lights will be installed and intersection improvements will be made to keep traffic moving through Southbrook.

201701 Road Works in Progress

About the Project

Ten years ago the intersection averaged 17,000 vehicle movements per day. Latest surveys show this has now increased to over 24,600 movements per day, causing congestion and delays for motorists.  

To improve traffic flow, traffic lights will be installed and intersection improvements will be made to improve traffic flows through Southbrook.  

Isaac Construction will be undertaking the work. The intersection upgrade is expected to be completed in late May 2017.

Benefits include:

  • Improved safety through the intersection
  • Safer access for people on bikes
  • Improved pedestrian connections and safety
  • Improved turning safety

How this work will affect you:

Access - there will be times during the work when vehicle access to properties will be restricted. Access will be restored by the end of the working day. The contractor will notify affected residents before any access restrictions.

Thank you for your patience and co-operation while we complete this work. The contractors will do what they can to keep noise and disruption to a minimum.

Work to Date

Progress update 17 February 2017

Work underway

This week Isaac Construction has installed the first of the signal poles on the north-east and run the new ducting to the pole base. The footpath on the north-east quadrant has been completed and sealed and construction of the footpath on the south-east corner has also continued.

A new water sub-main has been installed behind the new kerb and channel on the south-east quadrant but has not yet been connected.

Upcoming work

Next week the installation of the new water sub-main will be completed on the south-east quadrant, with the connection to the existing water reticulation being made.

The signal poles will be installed on the south-east corner, the road shoulder on eastern side of Southbrook Road will be sealed and the footpath will be finished and sealed on the south-east corner.

Next Monday 20 February (weather permitting) work will be carried out to replace the existing water-sub-main across South Belt and to install the signal ducting across the road at the same time. To allow this work to be carried out, there will be a lane closure on South Belt, east of the roundabout. If conditions are not favourable then Tuesday is the backup day. While this work is carried out vehicles will only be able to travel in an easterly direction between the roundabout and Newnham Street. Newnham Street southbound vehicles will be detoured via Charles Street for the day.  A letter drop has been carried out to affected properties in advance of this work.
