The A12 at Ardleigh was closed in both directions for nearly two hours this morning as police talked down a man standing on a bridge over the dual carriageway.
Essex Police were called to the scene, at junction 29, shortly before 6.30am, following reports from members of the public saying a man was standing on the bridge.
Officers talked to the man, and encouraged him to move to a place of safety.
A spokeswoman for the force said the man received treatment from healthcare professionals following the incident.
She added the road reopened at 8.15am.
