Work has been taking place at Kendall’s Cutting about four kilometres north of Milton since September and involves widening the road shoulders to reduce the risk of rock falls onto the highway at a cost of $2.3 million.

Motorists are advised the speed limit will be 80km/h through the work site with both lanes open during the holiday shut down.

The speed limit will be reduced to 40km/h between 7am and 5pm on weekdays when work resumes on Monday January 19, with the exception of the Australia Day weekend.

Member for South Coast Shelley Hancock said the project is expected to be completed in late March, weather permitting.

The project was due to be completed in November, but there have been hold-ups due to ongoing wet weather.
