"This will allow us to remove all or most of the cones and barriers, and fully open the intersection up before Christmas," Mr Seakins said.
The final layer would then be installed over five nights from January 15.
Work to upgrade the intersection and four-lane the remainder of Nixon St had been ongoing throughout the year, meaning disruption for residents, commuters and nearby businesses.
It coincided with major work throughout 2016 at the other end of Kensington Ave, where the New Zealand Transport Agency was installing a roundabout at the intersection of State Highway 1 (Western Hills Dr).
This roundabout is set to be finished by Christmas as planned.
