Four-mile queues remain on the northbound carriageway of the A12 after a lorry overturned during a crash.
The crash happened on the exit ramp at junction 25 for Marks Tey, by the roundabout for the A120, around 5am this morning.
Police, ambulance and fire crews were all called to the scene.
The exit slip was closed throughout the morning, while one lane of the A12 was also closed near the scene.
The eastbound A120 was later closed between Braintree and Marks Tey for more than an hour.
Recovery crews had righted the lorry by 11am, before reopening all of the roads around 11.15am.
Heavy traffic remains on the northbound A12 as far as Kelvedon, however.
A spokesman for the East of England Ambulance Service said one person was transported to Colchester General Hospital for further assessment and treatment.
