Transmission Gully PPP

Overview:

• The Transmission Gully PPP project involves constructing a 27-km four-lane—two in each direction—motorway from MacKays to Linden, with interchanges at MacKays Crossing, SH58, eastern Porirua (James Cook), and at Kenepuru.
• The project is part of the Wellington Northern Corridor and is a vital cog in the region’s transport system, and is designed to provide a critical and resilient lifeline to Wellington in the event of an earthquake or other major disruption.
• Transmission Gully is the first roading project in New Zealand procured through a Public Private Partnership (PPP) model, where the New Zealand Transport Agency (NZTA) has set performance targets for Wellington Gateway Partnership (WGP) on elements such as seismic resilience, incident response, and trip time reliability.
• The project is part of the roads of national significance (RoNS) programme that is key to the government's National Infrastructure Plan and financial close for the design, construction, and financing was obtained on 29 July 2014 with completion scheduled for 30 April 2020.
