Kent Street shared use path

In May, the Kent Street shared user path was realigned, and work will now start to build a retaining wall along the southern section near Dutton Park station.

Construction out of hours

  • Standard construction hours are between 6.30am to 6.30pm, Monday to Saturday
  • Works may also be required out of hours due to construction methodology, to reduce impact to drivers and for the safety of the community and our workers.

  • Delivery of construction machinery, concrete, equipment and materials to and from site
  • Site and service investigations and utility relocation works
  • 24/7 works within the rail corridor over weekend closures.
