The Wellington Northern Corridor covers a 110km stretch of road from Levin to Wellington Airport. It is one of the government’s seven Roads of National Significance.
The Wellington Northern Corridor(external link) is made up of the following projects (south to north):
- Inner City Transport Improvements from the Airport to the Terrace Tunnel
- Aotea Quay to Ngauranga
- Linden to MacKays (Transmission Gully)
- Kapiti Expressway (MacKays to Peka Peka, Peka Peka to Otaki)
- Otaki to Levin
Public Private Partnership for the Transmission Gully project
In November 2012, the government confirmed that it had approved a request by the NZ Transport Agency to proceed with the procurement of the Transmission Gully project through a Public Private Partnership (PPP).
The NZ Transport Agency has now moved to next stage of procurement. Subject to final borrowing approval, a PPP contract is expected to be awarded in mid-2014. Construction would begin in late 2014, and the highway would open for traffic by 2020.
