The A272 Cowfold Road has now been cleared after being partially blocked in both directions following a collision this afternoon (September 20).
The incident took place between Bolney Cross and Coach House Roundabout.
It is not known is anyone is injured at this time.
Motorists have faced long delays on the road since temporary traffic lights were introduce on September 9.
Last week we reported how one mum was forced to abandon her car to try and get her children to school after being prevented by the disruption on the A272 both ways.
