Waterview Connection

The $1.4 billion Waterview Connection project will complete Auckland’s Western Ring Route. The project involves almost five kilometres of new motorway including two parallel tunnels, 2.4 kilometres in length, and interchanges to connect to the Southwestern Motorway at Mt Roskill and to the Northwestern Motorway at Great North Road. It will be the largest, most expensive and most complex roading project ever undertaken in New Zealand.

The Western Ring Route will provide a 48-kilometre alternative to State Highway 1 and the Auckland Harbour Bridge. Construction has started with the project expected to be completed by the end of 2016.

Part of the Well-Connected Alliance Team (Comprising NZTA, Fletcher Construction, McConnell Dowell Constructors, Parsons Brinkerhoff NZ, Beca Infrastructure, Tonkin and Taylor, Boffa Miskell and Obayashi Corporation), Warren and Mahoney is responsible for the architectural components of the project including the ventilation stacks, egress structures, pedestrian bridges and associated tunnel buildings.

Concept Design

Inspired by the aesthetic forms of Obsidian (volcanic glass) the concept design for the tunnel's ventilation stack has focussed on creating a faceted slender form of elegance and beauty. Its full sculptural appearance is appreciated on approach from the motorway as the stack’s slanted form extends down to the motorway serving as the portal’s dividing wall and prominent marker.

The notion of extruded boxes shifting in and out of the tunnel express traffic movement through the tunnel, its glazed ends with vertical patterning referencing the striated basalt columns remnant from cooled lava of early volcanic eruptions present across the site.

"This is one of the most complex and exciting transport projects ever to be undertaken in this country. The project is hugely important, not only in terms of the benefits it will bring to Auckland, but to the whole country."
