Night works have been underway since October 31 in preparation for the change, and more will be needed after the traffic switch.
These works are scheduled to continue until Thursday next week and will take place from approximately 7pm until 5am the following morning.
Lane closures will be necessary during night works. The traffic switch is not expected to impact the existing pedestrian and cycling route throughout the site.
People are encouraged to take extra care driving through the Bay Link site while road users adjust to the new layout.
Motorists should reduce speed and follow the directions of traffic management staff and signs.
A 30km/h temporary speed limit is in place around the Bayfair roundabout for the duration of the Bay Link project to protect road workers and ensure the safety of everyone travelling through the roundabout.
Waka Kotahi NZ Transport agency acknowledges Bayfair Shopping Centre and Golf 360, and thanks local businesses, residents and motorists for their patience while this work is carried out.
In the event of unsuitable weather or other unforeseen circumstances, work may be postponed.
