Improving access to, from and around the airport
The New Zealand Transport Agency is upgrading the State Highway 20A / Kirkbride Road interchange. The transformation of the Landing Drive roundabout into an intersection (controlled by traffic lights) occurred on Friday 18 May.
As part of the SH20A to Airport project, the New Zealand Transport Agency has upgraded the Landing Drive roundabout to a fully signalised intersection. Work started in March 2017 and took just over 12 months to complete.
The new eight lane intersection will increase capacity and improve safety and journey reliability to, from and within the Airport precinct. The Landing Drive intersection is where SH20A (also known as George Bolt Memorial Drive) ends and transitions into the airport road network.
The intersection has 8 lanes for north and south-bound traffic flow with dedicated left and right turn lanes. Landing Drive and Verissimo Drive has dedicated turning and straight through lanes. This improves the flow of traffic entering and exiting the industrial areas. The upgrade supports the significant traffic growth and development in the wider Airport Oaks area.
Please be patient, obey the lights and allow a little extra time to stop on the red light.
Changes to the intersection were necessary because the heavy traffic flows to and from the airport meant the roundabout did not function efficiently. For example, at Landing Drive, the strong north/south flow meant the roundabout was not balanced and didn’t work as well as it could.
The solution is a new 8-lane intersection with permanent traffic lights which will improve safety and journey reliability. The transformation from a roundabout into an intersection (controlled by traffic lights) occurred on Friday 18 May.
The upgrade of the Landing Drive intersection is part of ongoing improvements to SH20A, which is the primary route between Auckland Airport, its business district, and the greater Auckland area. Other improvements include the upgraded Kirkbride intersection, with its trench underpass separating local and airport traffic.
