Motorists can expect delays on the Princes Highway this week, while pavement investigation work is carried out in Wandandian, Milton and Burrill Lake.
On Monday night from 7.30pm to 1am, works at Wandandian will take place between Bollerang Creek and Tullawalla Trail.
On Wednesday night from 7.30pm to 1am, work in Milton will be carried out between Matron Porter Drive and Warden Road.
On Thursday from 7.30pm to 11pm, work in Burrill Lake will be carried out at the intersection of the Princes Highway and Wallaroy Drive.
The work will look at the current state of the road surface and identify sections which may require resurfacing.
To minimise impact to motorists, work will be carried out at night, weather permitting.
Single lane closures, traffic control and a reduced speed limit of 40 km/h will be in place for the safety of workers and motorists.
Motorists are advised to drive to the conditions, follow the directions of signs and traffic control and allow up to five minutes additional travel time during work hours.
Roads and Maritime Services thanks the community for its patience while work is carried out.
