"Snow clearing equipment will be at key locations and traffic conditions will be monitored.
"Crews will carry out salt spreading throughout the night to help reduce the likelihood of black ice forming with the low overnight temperatures.
"Portable and permanent VMS boards will be utilised to provide motorists with real-time traffic information."
The last days of winter have brought a cold snap to the Lithgow region and the Bureau of Meteorology is forecasting tops of just 8 degrees Celsius on Wednesday and 8 on Thursday.
It will be even colder in Oberon with forecast tops of just eight and six, respectively.
Motorists are advised to take additional caution and drive to conditions.
Snow and black ice create additional road hazards and motorists should limit travel where possible, reduce speed, limit braking and keep an increased distance between vehicles in front.
