UPDATE: South Yorkshire motorway partially re-open after crash
The M18 at Doncaster has partially re-opened after a crash that the air ambulance was called to.
The northbound stretch between junctions 3 and 4, between Loversall and Armthorpe, Doncaster, was closed earlier while emergency services were at the scene.
One of the lanes has since re-opened and traffic is slowly passing the scene, but there are queues.
