First public private partnership road project in New Zealand
The Transmission Gully Motorway is part of the 110 kilometre Wellington Northern Corridor Road of National Significance.
Transmission Gully is New Zealand’s first road project to be procured through a public private partnership.
The Wellington Gateway Partnership has been engaged to design, construct, finance, operate and maintain the new Transmission Gully Motorway for 25 years.
The consortium includes Pacific Partnerships (sponsor and equity investor), CPB Contractors (design and construction), and Ventia (operations and maintenance).
The 27 kilometre four lane Transmission Gully Motorway is addressing safety and projected capacity concerns on New Zealand’s existing State Highway 1. The design includes 25 bridges and focuses on driver safety and resilience to seismic activity.
The motorway was opened in March 2022, providing a more efficient connection and supporting the local economy.
