"I'd also like to commend members of the public who provided assistance at the scene of this collision and our officers and other emergency services for their caring and professional approach in these very tragic circumstances.

"Life is so precious and so fragile."

Democratic Unionist Party (DUP) leader Sir Jeffrey Donaldson said: "Our thoughts and prayers are with all involved in this tragic incident and the families and communities impacted by such a devastating loss.

"We also think of the emergency services who attended the scene and the health service staff caring for those injured."

'Incredible loss, grief and sorrow'

Police said no other vehicle was involved in the earlier crash in which Ms Quinn died.

Officers received a report just before 13:30 GMT on Monday that a blue Mercedes car had left the east-bound carriageway, near the Stangmore junction.

Emergency services attended but the woman died later in hospital as a result of her injuries, police said.

CannyMan Community Arts said Ms Quinn was a founding member of the organisation and that it was "difficult to find words to articulate the incredible loss, grief and sorrow felt at this time".

"Coming from a family steeped in music and arts and with an abundance of talent, Imelda had the foresight to create an organisation that would celebrate the arts and provide opportunities to showcase talent within the Galbally community," it added.
