Waterview Tunnel
The Waterview Connection is Auckland's most significant transportation Project since the opening of the Harbour Bridge in 1959.
The Western Ring Route is a 48km motorway that bypasses central Auckland to the west. It provides an alternative to State Highway 1 for north/south travel through the region as well as more efficient connections between Auckland’s business and employment hubs.
The Waterview Connection provides the missing link between the Southwestern (SH 20) and the Northwestern (SH 16) motorways.
Construction began in late 2011 and involved the construction of two parallel 2.5 km road tunnels using a 14 metre Tunnel Boring Machine.

Our Scope
Marshall Day Acoustics was the primary Acoustic Consultant on the Project, managing noise and vibration issues through the concept design, notification, developed design and consenting stages, including the Board of Inquiry hearing.
The $1.4b Waterview Connection is the largest and most ambitious roading project ever undertaken in New Zealand. It involved:
Building two 2.4km long, 13.1m diameter bored tunnels, each to carry three lanes of traffic
Connecting the tunnels to the existing motorway network – SH 20 to the south and SH 16 to the north
Building six new road bridges
Building new recreational facilities including sports fields, skateparks and basketball courts
CHALLENGES
Preparation for the start of tunnelling involved a significant amount of rock breaking close to residential areas. This challenged the project to stay within its construction noise limits.
At the northern (Waterview) end of the project, work required construction of new ramps to connect the new motorway to State Highway 16.
