We are very excited to add more events to the IECA Aust. Calendar, this time as a one-day study tour. IECA Aust. is working with the CPB HEB JV team to host a visit to the Transmission Gully project, one of the largest and most complex civil construction projects currently underway in Australia and New Zealand.

Built to demanding specifications, the design and construction of the Transmission Gully motorway reflects the need for another route between Wellington and the lower and central North Island that will be safer and more reliable for motorists and better able to resist and recover from earthquakes and storms.

The project covers 27km of new motorway and is highly complex, with difficult and steep terrain requiring large-scale earthworks during construction of the project. 25 new structures equating to a total length of more than a kilometre will be constructed along the route. The largest of these, the Cannons Creek Bridge, will stretch 230 metres in length and sit 60 metres above the valley floor.

The $850 million Transmission Gully motorway is being delivered as a Public Private Partnership (PPP) by Wellington Gateway Partnership in partnership with the New Zealand government. A key part of the Wellington Northern Corridor ‘roads of national significance’, the project is one of the most significant single pieces of new road construction in the lower North Island.

The project has significant constraints to environmental management, particularly with regard to erosion and sediment control. This has necessitated the development of an integrated and creative methodology for ensuring appropriate environmental protection during construction.

This is a one in a lifetime opportunity to see the challenges of construction first hand and discover some of the innovative ways that the project team has managed erosion and sediment control during earthworks.
