Police are lifting the road closures to the A130 southbound as it has been established that a suspected grenade is in fact an imitation.
Experts from the Colchester Army barracks were called to the scene after a member of the public spotted the suspicious object during the rush hour this morning (October 28).
Motorists had been advised to avoid the A130 junction with the A127 at Rettendon as police had closed all approaches.
Congestion should start to ease.
