A 23 year old woman is fighting for her life in hospital after a serious two vehicle crash just south of Harriston.
The OPP say one vehicle was eastbound on Wellington Road 109 when it was hit by a northbound van coming from Wellington Road 5 just before 3 PM Thursday.
The car ended up crashing into a tree in a nearby ditch.
The 23 year old woman from Arthur who was driving the car was airlifted to a London hospital with serious injuries.
The 18 year old van driver from Clifford was not hurt.
The intersection was closed for about five hours as police looked into the crash and the investigation continues.
