Geotechnical investigations will be carried out for about one kilometre on the westbound lanes of the highway between 7.30pm and 5am Sunday to Thursday for four weeks, weather permitting.
Traffic control, lane closures and a reduced speed limit of 40km/h will be in place during work hours for the safety of workers and motorists.
Oversize overmass (OSOM) vehicles with a load width more than 4m will not be able to travel westbound during work hours due to lane closures.
Motorists are advised to drive to the conditions and follow the directions of signs and traffic control.
