Traffic Notice 26 - 29 June: Southern Corridor Improvements

Tuesday, 27 June 2017

Welcome to the traffic notice for the week of 26 - 29 June for the

Southern Corridor Improvements Project 

Traffic notices provide a brief overview of likely traffic disruptions for the following week. Full closures are also advertised in the Weekend Herald. Traffic notices are complemented by monthly construction updates and quarterly newsletters.


  • Narrowed lanes and 80 km/h speed limit northbound on the motorway between the Papakura Interchange and Hill Road.
  • Narrowed lanes and 80 km/h speed limit southbound on the motorway between Orams Road and the Papakura Interchange.
  • Full closure of Orams Road Bridge to all traffic and pedestrians.
  • Narrowed lanes and 50 km/h speed limit both directions on Great South Road at Takanini Interchange, between the northbound off-ramp and the southbound on-ramp.



  • Monday 26 June -  Night closure of the full motorway southbound from the Takanini Interchange to Papakura Interchange. This includes the southbound on-ramp at Takanini.
  • Tuesday 27 June - Wednesday 28 June - Night closure of the full southbound motorway between the Takanini off-ramp to the Takanini on-ramp.

Local Roads

UPCOMING WORKS (dates may be subject to change)

  • Monday 3 July - Night closure of the full motorway southbound from the Manakau Interchange to the Takanini Interchange. This includes closure of the Redoubt Road on-ramp, Lambie Drive eastbound on-ramp, and SH20-1 Link.
  • Tuesday 4 July - Night closure of the full motorway southbound from the Takanini Interchange to Papakura Interchange.This includes the southbound on-ramp at Takanini.

Night work on the motorway this week involves installing bore piles to support the new southbound bridge at Great South Road and general road maintenance. If it rains or ground conditions are too wet, work will be postponed until the next available dry night.

To construct an additional fourth southbound lane from SH20 to Hill Road, the eastern span of Orams Road Bridge will be lengthened. Orams Road Bridge will be temporarily closed to all pedestrians and traffic while this work takes place from April 22 to October 2017.

Work during the night will allow our crews to operate equipment safely while adjacent to the existing traffic lanes. Work in the shoulder and median work zones will continue during the daytime next week, but this will not affect traffic movements.

Night closures are typically from 10pm at night to 5am in the morning. Detours will be in place to take motorists along local roads, leading back to the next motorway interchange. All detours will be clearly signposted, and maps of the typical routes can be found on our website at http://www.nzta.govt.nz/projects/southern-corridor-improvements/traffic-notices/.  Please allow extra time for your journey at night.

With the lanes narrowed, there is less time to react to other vehicles and it is important that motorists keep to the 80 km/h speed limit past our work areas. There will be ongoing truck and project vehicle movements accessing the shoulder and median work sites. Keeping both motorists and our team members safe as possible is imperative and we need everyone's help to do this.

As always, we will be doing our best to minimise effects of these works on the public as much as we can.

We thank you for your patience as we work to improve journey reliability and safety along the Southern Corridor.
