The road between the Black Down roundabout on the Uckfield by-pass and the Batts Bridge roundabout, Maresfield, was closed earlier this afternoon after an accident.
The fire service was called to the crash involving two vehicles at the Black Down roundabout at about 1.45pm. They cut a man from one of the vehicles and he was taken to hospital, according to Steve Burgoyne from Uckfield Fire Station.
The firefighters left the scene about three-quarters of an hour after arriving. The road remained closed with the police still in attendance awaiting the arrival of recovery people.
