Travellers could expect lane closures and traffic diversions while the embankment works were undertaken.
Completion of the embankment is expected in April.
The interchange will be a standard diamond interchange with a four-lane bridge over the toll road and an exit north into Pāpāmoa East to directly service the future Golden Sands Town Centre.
The interchange will also provide a major escape route in the event of a tsunami and is expected to be finished in early 2026.
It will also enable faster travel for motorists driving between Pāpāmoa East and Tauranga, Mount Maunganui and the wider region, including Te Puke. It will also provide a connection to the Rangiuru Business Park once that is operational.
Total investment for the project is expected to be about $90 million.
