Temperatures dipped to as low as -8°C in parts of the province creating problems for motorists.
Stephen Smyth from the Road Service has been outling the key routes which are affected.
"The keys roads are east and the south Belfast extending down to Downpatrick and over to the Ards peninsula.
Also higher routes in the north and west of province continue to have compacted snow which is causing difficulty."
Meanwhile, flights to Northern Ireland continue to be disrupted by the weather.
Belfast International say flights to and from Edinburgh have been cancelled due to the weather, while flights from Leeds have also been delayed.
Hundreds of passengers who were left stranded overnight on Wednesday due to flight cancellations at UK airports are continuing to try to get to Northern Ireland.
Easyjet flights from Luton and Stansted into Belfast International were both grounded due to the weather, along with a flight from Malaga in Spain.
At the George Best Belfast City Airport one flight from Liverpool was cancelled.
