that was shortlisted to earn the World Architecture Festival award for transportation in November 2018.
Built in Auckland, New Zealand, the team finished the construction of its twin tunnels and connecting infrastructure in 2017 and has since projected a major change in travel patterns for its citizens.
The $1.4 billion project completes Auckland’s Western Ring Route. It involves almost 5 kilometers of new motorway including two parallel tunnels at 2.4 kilometers in length and interchanges to connect to the Southwestern Motorway at Mt Roskill and to the Northwestern Motorway at Great North Road.
Consisting of green spaces, walking tracks, children’s playgrounds and a network of shared cycling paths, the pedestrian bridge also has an air filtration system that transforms car exhaust, or air pollution, into clean air.
The tunnel’s ventilation stack slants and extends down to the motorway, serving as the portal’s dividing wall and prominent marker. Watch the featured video to get a view from each angle.
