There is a lot of police activity and fire crews are driving up and down the road.
You cannot see the crash site as the woodland is so dense but there are people climbing through to try to see if they can see more.
Now that the evening is setting in, you can just about make out the lights being used to help investigate the scene through the dense woodland.
The police have cordoned off the road, stopping any traffic from coming in.
Still no word from the force over the number of people involved in the incident.
