State Highway 20B Early Improvements Update

22 January 2021

Kia ora koutou,

State Highway 20B Project Updates keep you up-to-date with project progress and upcoming physical works on State Highway 20B (SH20B).

Night time Stop/Go Traffic Control for SH20B

No more full road closures are planned for night works on SH20B.

From next Sunday 24 January, between 9pm and 5am, Sunday to Thursday nights, we will have Stop/Go Traffic Control and traffic lights in place along SH20B.  This will mean that the new electric Airport Link bus service, along with all vehicles, will have access, every night, along SH20B between the SH20 Interchange and Auckland International Airport.

However, as we are still working on the road, there may be delays as we are move plant or stop work to let vehicles through. Please allow extra time for your journey.

Project overview

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.
