One lane of the A12 has been closed after a car left the road and crashed into a ditch.
Part of the northbound carriageway is shut between the junctions for Eight Ash Green and Spring Lane following the accident.
It is understood to have taken place at around 2pm this afternoon.
Traffic is slow in the area and drivers should allow extra time for their journeys.
Three fire crews from Colchester, Manningtree and Wivenhoe were set to the scene.
Upon arrival they set to work releasing one person from the vehicle.
They were left in the care of the ambulance service at 2.45pm.
