Project introduction

20Connect will improve journey reliability along State Highway 20, State Highway 20A and State Highway 20B to provide more choice for people when travelling around southwest Auckland, including to and from the airport.

Weekend road closures in November

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

We are planning to close State Highway 20B (SH20B) to through-traffic between the Hape Drive roundabout and the SH20 Interchange for two consecutive weekends to allow essential work to proceed that cannot take place safely during normal working hours. The road closures will take place in the following dates and time:

9pm Friday 13 November to 5am Monday 16 November.

9pm Friday 20 November to 5am Monday 23 November. 

Manukau Memorial Gardens will remain open, and resident/business access to Campana and Prices Roads will be available from the eastern approach to SH20B. Access to cyclists and walkers will also be maintained throughout the weekend.

During the closures the 380 Airporter bus service will be detoured along alternative routes. Some delays can be expected during this time. Please plan ahead and use the journey planner for up-to-date travel times.

We apologise in advance for any inconvenience and will use best industry practices to minimise disruption.

This is an advisory and more information will follow in the coming weeks.


Safer speed review and bus/T3 lane bylaw

Waka Kotahi NZ Transport Agency is improving State Highway 20B (SH20B) to provide a safer journey experience and more reliable travel choices with new priority lanes in each direction between Pukaki Creek Bridge and the interchange with State Highway 20.

SH20B improvements are the first step of the Southwest Gateway programme, which will provide better public transport, walking and cycling facilities as well as safer and more efficient movements in Southwest Auckland.

To provide safer and more reliable journeys on SH20B, we want to hear from you on the proposed speed limit change from the current 100km/h to 60km/h and the bylaw on the dedicated bus and Transit 3 (T3) lanes.

Provide feedback on the proposed changes 

Feedback closes on Wednesday 4 November at 5pm.

Night works on SH20B

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

Our normal working hours for the SH20B project are between 7am and 5pm from Monday to Saturday. However, due to time lost as a result of Covid-19 and to honour our commitment to timely completion of the project by early next year we are expanding our working hours into the night.

The night works will also ease pressure off the network, minimise disruption during peak hours and offer a safer working environment for construction staff.

The road will remain open to people on foot and people on bikes.

If this work is delayed due to weather or any unexpected road conditions it will roll to the next fine night. We apologise in advance for any inconvenience and will use best industry practices to minimise disruption.

As a live construction site, the speed limit is 50km/h. Please drive with care and watch out for people on foot and on bikes.

For more information, see the weekly timetable below:

Due to the road works on SH20B, expect delays and allow extra time for your journey for those using Bus Route 380. Thank you for your understanding. 

Project overview

20Connect will improve journey reliability along State Highway 20, 20A and 20B and provide more choice when travelling around southwest Auckland, including to and from the airport.

Improvements identified on the state highway network will enhance the public transport system, cater for freight and cyclists and improve access to growth areas adjacent to the state highway.

20Connect is part of a wider programme of works called the Southwest Gateway. This programme is being carried out by the Transport Agency, Auckland Transport and Auckland Airport.

Project area map

Map showing project area.

We will identify how we can

  • improve capacity and connections on or beside the state highways
  • for private vehicles, public transport, walking and cycling
  • improve safety
  • reduce the effects on the environment and treasured places/taonga
  • identify ways to better manage traffic flow on the network
  • maximise the use and reliability of the existing network and its ability to cope with unplanned events.

Project stages

The project will be delivered in stages over the next 20 years.

Stage 1: Early Improvements by 2020/2021:

  • priority lanes to increase the efficiency and reliability of public transport and that will connect with improvements at Puhinui Station
  • new intersections on SH20B to improve access and safety
  • improved walking and cycling facilities, localised road widening and resurfacing, drainage and stormwater treatment on SH20B.

Stage 2: Long-Term Improvements from 2021:

  • state highway widening to support rapid transit
  • increased access to the state highways to free up local roads.

Current issues

  • It is difficult to estimate how long the journey to this area will take, this needs to be more reliable for both people and goods.
  • People have limited options as to how they travel to and from this area, people need to have more choice.
  • There is extensive growth planned in this area. This growth will increase the pressure on the state highways. The capacity, connections and management of the network needs to be improved to support the planned growth no matter how people choose to travel.

What will be investigated?

The 20Connect project will develop a single stage business case to identify ways to address these issues. Potential improvements that will be investigated will include:

  • Improving the capacity and connections on, around or alongside the state highways for cars, trucks, buses and bicycles.
  • Optimising the existing network.
  • Providing more choices as to how people and goods travel to and from this area.
  • Identifying ways to influence the demand on the network.
  • Ways to help people planning their travel and choosing travel options.

We expect the single stage business case to be completed by late 2018.

Early improvements

While we’re busy identifying improvements to deliver in the longer-term, we know there are some issues people are experiencing right now that need to be addressed.

We’ve identified that providing bus priority along SH20B can give immediate benefits to people travelling in this area. These improvements will connect with other early improvements identified with the Airport to Botany Rapid Transit project(external link) and make the most of existing infrastructure and services to improve travel choices and journey experiences. We aim for these to be delivered by 2020/2021.
