The SH20B Construction team is putting through their stretching and team building paces in a half day Back To Work session at Mangere Memorial Hall. Being `switched on and work-fit' after a holiday break is an important part of SH20B safety culture.

State Highway 20B Early Improvements Update

15 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).

Happy 2021 from the SH20B team

The SH20B Early Improvements project team wishes you a Happy New Year as we resume major works along SH20B.

From Tuesday 5 January, we have been back at work planning and activating day and night works as we push to acheive the completion of major aspects of the project.

Activities over the next four to five months will include drainage, kerb and channel installation, local road construction, asphalting and line-marking, landscaping and fencing.

Key to the project will also include the set-up of two new signalised intersections, central barrier protection and the completiion of the wide new shared user paths. Civil engineering work on the Waokauri Bridge is scheduled for completion by early February.

Utimately, public transport will become an easier and quicker option for commuters with dedicated bus lanes ensuring resilient connections between the Puhinui Interchange and the Auckland International Airport.

We are looking forward to a busy and safe summer as we see the final shape of the new highway becoming operational. Thank you for your patience!

Safety

• All traffic must turn left both into and out of properties and side roads. Manukau Memorial Gardens is exempt from left-turn movements
• Vehicles turning into driveways and side roads on the southern side must watch for bikes and foot traffic on the temporary shared cycle and walking path
• The speed limit for SH20B is 50kph from Manukau Memorial Gardens to Tom Pearce Drive, except at crossing points and coned paving areas where the speed will briefly drop to 30kph. 

Looking Ahead

An ongoing comprehensive programme of night works is in place to enable trenching for utility services and ducting at multiple locations across SH20B. Posted detours will be in place. We apologise for any inconvenience and thank you for your patience.

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.
