Design and construction of the new motorway includes establishing sites, bulk earthworks and drainage, structures, pavement and commissioning.

Design of the Transmission Gully motorway has been driven by:

  • The Waka Kotahi Vision Zero for system designers design and operational specifications, including the roads of national significance guidelines
  • The New Zealand Government’s Safer Journeys 2010–2020 strategy
  • GreenroadsTM certification
  • The needs of communities along and around Transmission Gully and wider road network users.

The project is aligned with the Government’s objective to create a safe road system increasingly free of death and serious injury. We recognise our role as a safe system designer and the importance of our responsibility to create safer journeys for people travelling on the new motorway.
