Waka Kotahi NZ Transport Agency and Auckland International Airport Limited are upgrading State Highway 20B for better and more reliable travel options with a new shared path and additional priority lanes between Pukaki Creek Bridge and State Highway 20.

This project will integrate with improved transport facilities within the airport precinct along SH20B and at the upgraded Puhinui Station Interchange.

The project is the first step of the Southwest Gateway programme to provide better public transport, walking and cycling facilities with safer and more efficient freight movements to, from and around Southwest Auckland.

Fulton Hogan undertakes this work on behalf of Waka Kotahi.

Key early improvements on State Highway 20B to be delivered by 2021 include:

  • A safe place for people to walk and ride bikes
  • Safety improvements including central median barrier protection, improved lighting and a reduced speed
  • Improved pavement, drainage and stormwater treatment
  • Two improved intersections at Campana Road and Manukau Memorial Gardens.

Waka Kotahi NZ Transport Agency works to create transport solutions for all New Zealanders – from helping new drivers earn their licences, to leading safety campaigns to investing in public transport, state highways and local roads.
