The latest

28/9/2026 - The culvert units and inlet headwall was installed last week. Backfilling works, mass block retaining and cast in situ outlet headwall will commence. The temporary diversion road will still be in place for these works. Please reduce speed and drive with care.

About the project

Following multiple declared natural disaster events, the existing 750 pipe culvert and associated outlet headwall has been damaged at CH4980. Works have been approved to replace the existing 750mm pipe culvert with a new box culvert structure with new inlet and outlet structures including mass block retaining wall and new guardrail. In order to facilitate the construction works, a temporary single lane gravel access road will be constructed to deviate traffic around the site. The temporary single lane will be controlled with a combination of traffic controllers and traffic lights out of shift.
