This is part of the upgrade to the Baypark to Bayfair Link.
The $120 million project will link Baypark and Bayfair and complete the eastern corridor for the Bay of Plenty.
It is designed to ease congestion by separating state highway and local road traffic and improve on the journey time savings from the Tauranga Eastern Link.
It is also said to provide safer walking and cycling connections for pedestrians and cyclists.
Next week, the stormwater pipe diversion will require a manhole to be dug out and installed close to live traffic lanes.
In a statement, Waka Kotahi said while it would endeavour to minimise any disturbance for local residents, this work may generate some noise and vibration.
A range of new measures are in place to ensure the work could be done safely, to protect road workers, the people in their bubbles, and road users.
Road users are advised to travel with caution through the project site, reduce speed and follow the directions provided.
In the event of unsuitable weather, changes to New Zealand's national Covid-19 Alert system level that would impact these works or other unforeseen circumstances, work will be carried out on the next suitable nights.
Up-to-date information can be found on the designated NZTA website.
