A CRASH involving a motorcyclist and car on the A34 northbound has now been cleared and all lanes reopened.
There were queues stretching back for four miles earlier this morning.
One lane was closed from the A415 March Interchange to A4183 Abingdon North from around 9am until 10.30am.
A South Central Ambulance Service spokesman said paramedics were called at 8.09am to a collision between a car and a motorcyclist.
Earlier traffic feeds had indicated the incident had involved a van and car.
He added: "We sent an ambulance to the scene. Fortunately the rider had only sustained minor injuries and after initial treatment by the ambulance crew was then taken to the John Radcliffe Hosptial."
