State Highway 29A between the Baypark and Te Maunga roundabouts will be closed next weekend to allow for stone column ground improvement works to be carried out.
The NZ Transport Agency said the road will be closed from 9pm on Friday, November 9 to 4am on Monday, November 12.
It is also planned to close from 9pm on Friday, November 23 to 4am on Monday, November 26.
Detours will be in place along Truman Lane and Mangatawa Link Rd.
The columns will improve the ground conditions throughout the site so it can eventually take the weight of the two flyovers.
Installing stone columns involves putting vertical columns of gravel into the ground and using vibration to move the sand to make way for the stone.
This will be done using an 80-tonne crawler crane with a 3.2-tonne "vibroflot" attached - the vibrating element that carries out the compaction and delivers the stone.
Motorists are urged to use alternative routes where possible or plan travel outside of these hours to avoid the detour. This work is weather dependent and, if delayed, will be carried out on the next suitable weekends.
NZ Transport Agency thanked all road users for their patience and ongoing co-operation while construction of the Baypark to Bayfair Link project continued.
