Te Aranui o Te Rangihaeata – Transmission Gully motorway (SH1) opened in March 2022 and now provides a safe, modern and reliable route in and out of Wellington.
Transmission Gully changes the way people move around the region for the better – providing a resilient and reliable route in and out of Te Upoko o te Ika a Maui – Wellington, improving safety for everyone, offering better access for communities in eastern Porirua, improving access to the Hutt Valley through a connection with SH58 at Pāuatahanui, significantly reducing traffic volumes on the coastal SH59 route, and cutting peak travel times in and out of the capital by 7 to 15 minutes in each direction.
It is the first motorway in Aotearoa New Zealand to be constructed on behalf of the New Zealand Government under a Public Private Partnership (PPP) contract. The Government’s PPP contract is with Wellington Gateway Partnership.
The 27 kilometre motorway is also a key part of the Wellington Northern Corridor and is part of the Roads of National Significance programme.
