The Waterview Connection project is New Zealand’s largest and most ambitious roading project ever. Connecting the Southwestern and Northwestern Motorways (State Highways 20 and 16), it will complete a motorway ring route around Auckland, providing an alternative to SH1. More than just a highway, the end product will be a multi-modal corridor that provides pedestrian and cyclist routes, and public open spaces.
Half of the new motorway – 2.4km – is underground. A custom built tunnel boring machine (the tenth largest in the world) was used to construct twin, three-lane tunnels up to 40m below ground. With the tunnel excavation now complete, the mechanical and electrical fitout of the tunnels is underway.
The other main feature of the project is the Great North Road Interchange, which will connect the twin tunnels to the existing road network. Four ramps, totalling 1.7km in length will carry traffic to and from the tunnels onto Southwestern and Northwestern motorways.
Fletcher is delivering the project as part of the Well Connected Alliance, alongside McConnell Dowell Constructors, PB New Zealand, Beca Infrastructure, Tonkin & Taylor, Obayashi Corporation and the Transport Agency. The Alliance will also maintain and manage the connection – including the tunnels – for 10 years after it opens.
When the Waterview Connection opens in early 2017 it will have the biggest impact on the way people travel around and through Auckland since the opening of the Auckland Harbour Bridge in 1959.
