The A380 has been reopened after a bus carrying school children and a car collided at Telegraph Hill this morning.
Three fire crews, ambulance and police were called to the scene on the northbound carriageway at Kennford.
The crash occurred at 8am and left the woman driver in the Ford Ka unconscious and trapped in her vehicle.
The school bus was carrying children but there are no reports of any injuries and a replacement bus was called.
The female in the Ford Ka was freed by fire fighters at 8:30am and is now conscious, say police.
Traffic was diverted to the A38 and police warned motorists to take care as conditions are poor with lots of surface water and spray.
