Redoubt Road dynamic lanes Redoubt Road dynamic lanes

To reduce congestion, Auckland Transport (AT) will install dynamic lanes on a 350-metre section of Redoubt Road in Manukau, between the Southern Motorway offramp and Hollyford Drive.

Project status: Notify
Project zone: South

Project overview

On weekday afternoons, most vehicles on Redoubt Road are heading away from Manukau. They have to merge into one lane at the start of Redoubt Road, near the motorway offramp. This can cause significant delays.

Dynamic lanes will change the direction of the centre lane between 4pm and 7pm on weekdays. Removing that pinch point and allowing traffic to flow.


  • February to August 2019 - Investigation and design work
  • August to October 2019 - Public communications
  • October 2019 - November 2019 - Pre-construction work
  • May to June 2020 - Consultation on design changes
