The police serious crash unit will be investigating.
Prior to the fatality, police said there had been 127 crashes since 3pm yesterday.
National road policing manager Superintendent Steve Greally earlier said it was the law of averages that someone would die over the holiday period.
"Unfortunately, as tragic as it is, we do lose people at this time of year."
He said there were lots of reasons the crashes had happened, including speeding, driving with alcohol, and motorists answering text messages.
"Crashes do not happen if you're paying attention. It's as simple as that."
Mr Greally said the majority of the crashes were "very low level". Several of the others were serious but the people involved did not have life-threatening injuries.
"The crashes have had varying degrees of seriousness. There were a couple of crashes that were really serious but have since been downgraded - the people are out of the woods, they are going to be okay."
