Details

We will be constructing a new retaining wall at 13 Hackthorne Road from 2 March 2026 until the end of April 2026. Traffic management will be in place for the duration of the works.

While traffic management is in place, please note the following:

  • Two-way traffic will be maintained at all times.
  • There will be closures of the footpath and road shoulder in the work area. As a result, on-street parking will not be available in this section, and pedestrian detours will be provided.
  • We will maintain property access for residents, where possible, during the day. Our on-site team will communicate directly with affected residents regarding any temporary access restrictions.
  • At night, the site will be secured with fencing, and full property access for residents will be restored.
  • A 30km/h speed limit will be in place to ensure the safety of both our team and road users.
  • Please follow all signage and detours in place.
  • We will reduce the extent of traffic management as soon as it is safe to do so.
  • Please advise if you have any specific property access requirements e.g. medical visits, home help, large vehicle access, deliveries or planned works etc.
