The Desert Rd will close for two short periods tomorrow for damage assessment following a major truck crash last week.
The New Zealand Transport Agency said the road near the Waihohonu Bridge was currently down to one lane after the crash caused extensive damage last Wednesday.
The state highway will be closed for up to an hour and a half from 7.30am while structural engineers carried out a detailed assessment of the damage both on and off the road.
This will determine what future repairs were needed.
The second closure, for up to an hour and a half, from around 10.30am tomorrow will allow a temporary barrier to be installed to protect road users. This will enable the road to opened to two lanes.
