This event brings together earthworks and civil engineering professionals who wish to be inspired by the environmental activities undertaken to manage impacts from the O Mahurangi project.

O Mahurangi is a 7 km highway linking the Whangapāroa Peninsula to State Highway 1 with a new crossing over the Wēiti River. The Project runs through a mixture of farmland, exotic and native forestry, connecting into an urban environment.

With unique geological and ESC challenges, the team has found innovative ways to implement environmental controls across the site.

Come hear from the site team who will take attendees on a guided site tour of the project showing them the progress that’s been made, some of the challenges and have a look at the Wēiti River crossing, the first extradosed bridge in New Zealand.

We thank the O Mahurangi Alliance for supporting this event.
