State Highway 20B Early Improvements Update

12 February 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).

All private vehicles and through-traffic should detour and use SH20A during the weekend closure.

UPCOMING WEEKEND CLOSURE FOR SH20B - from 9pm Friday 26 February to 5am Monday 1 March

We want to thank you for your support for the first and second weekend closures in November 2020 for the road widening works. The full closures enhanced effective construction work and helped us keep the project on track with the project schedule.

We are now planning the third weekend closure of SH20B to through-traffic between the Tom Pearce/SH20B roundabout and the SH20 Interchange for one weekend in February for the pavement works along Waokauri Creek Bridge and other essential works that cannot take place safely during normal working hours.

The weekend closure will take place from

9pm Friday 26 February to 5am Monday 1 March.

Manukau Memorial Gardens will remain open, and resident/business access to Campana and Prices Roads including Colin Dale Park and Puhinui Reserve will be available from the eastern approach to SH20B.

People on foot and on bikes can access SH20B throughout the weekend.

AirportLink bus service will be operational as usual. But bus users may experience a slight delay during this time. Please plan ahead and use the journey planner for up-to-date travel times.

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.
