Officers and other emergency services arrived on scene and found that there had been a head on collision between a car and a mid-size sport utility vehicle. Two people have died as a result of the collision. Another person, who sustained serious injuries, has been transported to hospital. Speed is believed to be a factor in the collision.
The highway remains closed in both directions and is not expected to re-open for a number of hours.
