A lorry has jackknifed on the A120 causing severe delays to motorists in Essex this morning.

The accident has closed the eastbound carriageway near to junction 29 for the A12 Colchester bypass, causing tailbacks to stretch onto the A12 back to Dedham, with vehicles unable to get onto the A120.

It is also causing delays on the westbound carriageway on the A120 as people slow to look at the lorry.

Essex Police are at the scene and will remain until the vehicle has been recovered.

No-one is thought to have been injured in the accident.

Motorists are being urged to avoid the area and find an alternative route.
