The Transmission Gully motorway (Māori: Te Ara Nui o Te Rangihaeata) is a 27-kilometre-long (17-mile), four-lane motorway north of Wellington, New Zealand; it is part of the State Highway 1. Construction began on 8 September 2014, with completion originally scheduled for April 2020, but contractual negotiations and difficulties resulting from the COVID-19 pandemic caused delays.
