The Waterview Connection project interchange and tunnels will link the Northwestern and Southwestern Motorways to complete the Western Ring Route. It is planned to open to traffic in early 2017. The Western Ring Route will be a 47-kilometre-long motorway between Albany on the North Shore and Manukau in the south. It will deliver several benefits for Auckland and the city’s regional neighbours. It will give drivers a second motorway choice to the Southern and Northern Motorways (SH1) through central Auckland, improve access to important commercial and residential destinations, reduce traffic on local roads, and provide better links for public transport and for people who walk and cycle. The Waterview Connection is being delivered by the Well-Connected Alliance which includes the Transport Agency, Fletcher Construction, McConnell Dowell, Parsons Brinckerhoff, Beca Infrastructure, Tonkin & Taylor and Japanese construction company Obayashi Corporation.  Sub-alliance partners are Auckland-based Wilson Tunnelling and Spanish tunnel controls specialists SICE.
